This book was released on 1977 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The purpose of this manual is to provide an analytical method of evaluating the fire endurance of structures made of precast and prestressed concrete. The manual brings together information from many sources, and presents the data in a convenient form. Example problems illustrate the use of the design aids and principles outlined in the text. In recent years, building officials, architects, and engineers have become increasingly aware of the unreliability of results of fire tests. Through the use of the engineering principles outlined in this manual, a greater degree of reliability in predicting fire endurance of structures or assemblies can be achieved. It is the hope of the PCI Fire Committee that building codes will adopt provisions permitting engineering analyses as the basis for establishing the fire endurance of a structure. Building codes should encourage the use of such engineering analyses by permitting a reduction in the fire rating requirements when such analyses are performed. The Committee feels that this manual represents a landmark contribution to designers, building officials, and insurance underwriters who are concerned with fire safety of buildings. Not only does this manual present a rational design approach for the safety of precast prestressed concrete structures, but also it places precast and prestressed concrete in the forefront of a long overdue frontier -- that of structural design for fire resistance."--Page iii.

This book was released on 2018-01-31 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: PCI-124-18 The Precast/Prestressed Concrete Institute (PCI) first issued a manual for the design for fire resistance of precast/prestressed concrete in 1977. A second edition was prepared in 1989 and a third edition in 2011. The recommended design procedures in those three editions were based on fire test data and reports for precast/prestressed concrete dating back to the 1960s. Little has changed since then in fundamental design for fire resistance. While fire resistance is discussed in other publications as "calculated" fire resis- tance, those provisions have generally been prescriptive. That is, tables of information are used to select concrete mass or protection for steel. Since the first edition of the PCI manual, rational design, which is truly a fire resistance calculation procedure, has been demonstrated. Though not a standard, the first edi- tion of the International Building Code in 2000 referenced the procedures in the PCI fire design manual as being acceptable for prestressed concrete slabs not covered elsewhere.With the 2014 designation of PCI as an ANSI (American National Standards Institute) Accredited Stan- dards Developer, the material for fire resistance of precast and precast, prestressed concrete was deemed important enough to the precast concrete industry that the newest edition of the provisions would be developed in a consensus standard form. Thus, the design procedures would be referenced in the 2021 International Building Code as a standard developed through an ANSI consensus process.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this manual is to assist in the design for fire resistance of precast prestressed concrete structures. According to the ICC-ES Evaluation Report ESR-1997, fire-resistance-rated precast/prestressed concrete construction may be designed using this manual as an alternative method to what is specified in the 2006 IBC Section 703.3 and the 1997 UBC Section 703.3. Since the 2nd edition, much has been experienced and learned, resulting in the need for updating the manual to its current status. Several parts have been rewritten to clarify the text and some new material has been added, but nothing has been changed that would affect the character of the manual.

Book excerpt: Concrete has not been a competitive alternative for roof applications due to the heavy weight and construction complexity of concrete components, which results in being less cost effective than steel. Despite the advantages of structural steel roof systems, they have the following disadvantages: low fire resistance, being prone to corrosion, high maintenance cost, long lag period in steel orders, and increasing prices of steel. Most of these disadvantages can be addressed by using precast concrete components as they have excellent fire and corrosion resistance, low production and maintenance cost, and short order period. Recently more extensive use of precast/prestressed concrete components, which are fabricated off-site and then connected on-site, has been taking place worldwide since it shows significant benefits compared to the conventional poured on site concrete technology. Among others, the benefits are in accelerating the construction time, enhancing the quality of concrete works, improving its durability and in general generating competitive structural cost. Pre-grouted prestressing tendon, primarily in the form of single strands, was generally applied to transverse prestressing of deck slabs or other work. When pre-grouted prestressing strands are used for main tendon, more prestressing strands are required than when conventional multiple strands are used. Numerous prestressing strands therefore should be anchored in a limited anchorage region. Hence, attention should be paid in design for the arrangement of pre-grouted prestressing tendons and details of anchorage.This book entitled "Prestressed Concrete Design" aims to give an overview of the recent evolution in the design and construction of prestressed concrete worldwide. Several major trends are outline. A number of innovative techniques have been described to enhance both the structural performance and the durability of concrete. It will also address and focus on the extent to the use of structural and precast ecoefficient concretes in the applications which have been developed comply with current standards.

Available in PDF, EPUB and Kindle. Book excerpt: Advances in knowledge relating to fire engineering design of concrete structures have led to the development of rational design methods as an alternative for time-consuming and expensive full scale fire testing or the use of simple tabulated forms of fire resistance data. Rational design methods are also better able to accommodate the effects of continuity and restraint, and the location of reinforcing or prestressing steel can be optimised, particularly for prestressed construction where prestressing steel rapidly loses strength at high temperatures and elements tend to be more slender. However, rational design methods are unlikely to be warranted where the required fire resistance is less than about two hours for reinforced concrete and about one hour for precast prestressed concrete. This report summarises the existing state of knowledge and discusses possible design procedures ranging from selecting an appropriate design fire, to predicting the thermal and structural response of the member. Recommendations are also made supporting a review of existing New Zealand tabular forms of fire resistance data contained in MP9 for designing concrete structural elements.

This book was released on 1978 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: This method provides a means for predicting, by calculation, the resistance to fire of a reinforced or prestressed concrete element of construction, in accordance with 1959 French directives. The method is useful in allowing builders to design structures which show the degree of fire resistance required by the various French construction regulations in force. According to those regulations, only a test furnishes legal proof of fire resistance. French researchers hope this first step will lead to the acceptance in France of fire resistance calculations as legal proof of satisfactory resistance.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Precast prestressed concrete (PC) construction provides numerous advantages over traditional reinforced concrete (RC) construction, in terms of speed of construction, better quality control, cost-effectiveness, better space utilization, and optimized production. Owing to these advantages, the use of PC construction in the built environment has increased significantly in recent decades. While the structural behavior of PC members is well understood at ambient temperatures, there is a lack of understanding on the evolution of fire induced restraint forces in PC beams and their effect on the fire resistance of PC beams. Further, the fire resistance of PC members is currently evaluated using prescriptive design approaches which do not account for all critical factors governing the fire response of PC beams, including realistic restraint conditions, and therefore, current fire resistance provisions may not provide realistic predictions of fire performance.℗ Therefore, a detailed experimental and numerical study is conducted to evaluate the evolution of fire induced restraint forces and to quantify their effect on the fire response of PC beams. Fire resistance tests were conducted on four PC beams under restrained and unrestrained end conditions. Test variables included fire exposure, restraint conditions, load level, and concrete strength. The fire response of the beams was traced throughout the fire exposure duration by measuring sectional temperatures, beam deflections, and fire induced restraint forces. All four beams were designed as per current building code recommendations to have a fire resistance of 4 hours, however, all four beams attained failure within 2 hours of fire exposure. A numerical model was developed for tracing the fire response of PC beams under specified fire, loading, and restraint conditions. The model accounts for critical factors governing the fire response of PC beams including fire-induced restraint forces, cracking and crushing of concrete, spalling, material and geometric non-linearity, and geometry of the beam. For modeling fire-induced restraint forces a new efficient spring idealization framework for connections is implemented. Also, the cracking and crushing of concrete is captured by developing a new modified adaptive temperature-dependent failure envelope.℗ The developed numerical model was validated by comparing response predictions from the model with measured data in fire tests. Results from these comparisons show that the model can capture the fire response of PC beams with reasonable accuracy in both thermal and structural domains. The validated numerical model is applied to carry out a series of parametric studies on the effect of fire-induced restraint forces on the response of PC beams. The effect of cross-sectional shape, support conditions, the gap in connection, level of prestress, and concrete cover thickness on the evolution of fire induced restraint forces is studied for PC and equivalent RC beams. Results from parametric studies show that current prescriptive codes and standards may over-predict fire resistance of PC beams by as high as 100%, PC beams develop 5% to 20% lower restraint forces than equivalent RC beams, and for PC beams with gaps of more than 50 mm experience minimal restraint forces. Also, the fire-induced restraint forces can be either beneficial or detrimental and can significantly alter the fire response of the PC beam, and therefore, should be included in the design process. Based on the results from the fire tests and parametric studies, simplified recommendations are proposed for evaluating the fire resistance of PC beams.
