This book was released on 2007 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Beam-column joints are one of the most critical elements of reinforced concrete moment resisting frames subjected to lateral seismic loading. The older reinforced concrete buildings designed before the introduction of modern seismic codes in the early 1970's, in general, do not meet the current design code requirements. In particular, the beam-column joints in such existing buildings do not have appropriate detailing which leads to insufficient lateral strength or ductility to withstand the effects of a severe earthquake loading. Therefore, evaluation of the lateral load carrying capacity of existing buildings for subsequent retrofit is very important for the safety of the buildings. The economical aspect should also be considered during the design of a structure which is only possible if the behavior of the structure during an earthquake can be predicted. The focus of this research is to evaluate the shear behavior of reinforced concrete beam-column joints and to develop a suitable model that would predict the lateral load carrying capacity. Previous experimental studies and results have shown that the shear strength of beam-column joints depends on several variables including concrete strength, axial load ratio, joint geometry joint transverse reinforcement ratio, and displacement ductility. However, the current codes include the effects of all of these parameters in beam-column joint design. Therefore, previous analytical research is examined and this information is used to develop a shear strength model. The proposed model is mainly based on the shear strength model for columns developed by Sezen and Moehle (2004). The proposed shear strength model is verified with experimental test results. Overall, the model did a reasonable job of predicting the shear strength of reinforced concrete beam-column joints. The proposed model provides a simply tool for the analysis of existing reinforced concrete buildings subjected to lateral loading and to determine the amount of remediation necessary for satisfactory seismic performance.

Available in PDF, EPUB and Kindle. Book excerpt: Reinforced concrete deep beams are vital structural members serving as load transferring elements. The behavior of reinforced concrete deep beams is complex. Nonlinear distribution of strain and stress must be considered. Prior to 1999, ACI 318 Codes included an empirical design equation for reinforced concrete deep beams. Since 2002, the strut and tie model and nonlinear analysis have been required. However, both methods have disadvantages of complexity or lack of transparency. The objective of this study is to produce a simple, reliable design equation for reinforced concrete deep beams. A nonlinear finite element program, ATENA, was used for analyzing and predicting the behavior of concrete and reinforced concrete structures. First, applicability of ATENA was verified by developing the computer models of simply supported and two span continuous deep beams based on Birrcher's tests of simply supported deep beams. Tests by Rogowsky and Macgregor and by Ashour are the basis for the models of continuous two span deep beams. Those tests were selected because the researchers reported adequate details of the experimental program and on specimen behavior. Then a series of simply supported and two span continuous deep beam models were developed based on the details and geometry of Birrcher's beams. The computer models were used to investigate the following parameters: the compressive strength of concrete, shear span to depth ratios, longitudinal reinforcement ratios, web reinforcement, effect of member depth, and loading conditions. Finally, a proposed design equation for shear strength of reinforced concrete deep beams was derived based on the observed the behavior of reinforced concrete deep beam tests, the results of the analytical study, and a plastic truss model. The proposed equations were in good agreement with test values and provide an alternate approach to current design procedures for deep beams.

This book was released on 2011 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beam-column joint is considered a critical region in a structure when subjected to seismic load. Past earthquakes have shown that many of these structures behaved poorly and exhibited a combination of brittle failure at the joint and pullout of the beam longitudinal steel, leading to a rapid degradation of the joint and a precursor to a catastrophic collapse of a structure. Review of existing structures built prior to 1976 have determined concrete joints typically have little or no transverse reinforcement, discontinuous bottom beam reinforcement with insufficient embedment depth, and a common occurrence of column lap splice above the beam-column interface. Previous studies of rebar bond slip behavior, joint shear response, and joint interface - shear response were reviewed culminating in a study of various joint models simulating the behavior of deficient concrete beam-column joint subjected to a seismic load. An experimental test program consisting of three specimens was developed to test the behavior of deficient concrete beam-column joints. Specimen AB1 consists of deficient shear reinforcement at the joint, and will be tested to evaluate the behavior of a deficient reinforced concrete beam-column joint solely on insufficient shear reinforcement. Specimen AB2 is designed according to pre-1976 building standard and lacks sufficient rebar embedment of longitudinal beam reinforcement at the joint and has no shear reinforcement within the joint area. Specimen ACI318 is designed per the specifications of ACI 318-08, and will be used as the control specimen. Experimental results of the test program will eventually be applied as a baseline comparison to proposed state-of-the-art retrofit schemes aimed at enhancing the overall seismic performance of deficient reinforced concrete beam-column joints.

This book was released on 1971 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: Behavioral equations were developed for reinforced concrete deep beams, especially in the realm of shear capacity. A series of static and dynamic beam tests was performed to aid in the development of this objective. Static shear behavior equations for deep beams were derived on the lower boundary of reinforced concrete deep beam data represented by research from this report and other research comprising 73 tests. Equations for a total static shear capacity are given which conservatively predict shear capacities of the beam tests considered. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The first textbook on the design of FRP for structural engineering applications Composites for Construction is a one-of-a-kind guide to understanding fiber-reinforced polymers (FRP) and designing and retrofitting structures with FRP. Written and organized like traditional textbooks on steel, concrete, and wood design, it demystifies FRP composites and demonstrates how both new and retrofit construction projects can especially benefit from these materials, such as offshore and waterfront structures, bridges, parking garages, cooling towers, and industrial buildings. The code-based design guidelines featured in this book allow for demonstrated applications to immediately be implemented in the real world. Covered codes and design guidelines include ACI 440, ASCE Structural Plastics Design Manual, EUROCOMP Design Code, AASHTO Specifications, and manufacturer-published design guides. Procedures are provided to the structural designer on how to use this combination of code-like documents to design with FRP profiles. In four convenient sections, Composites for Construction covers: * An introduction to FRP applications, products and properties, and to the methods of obtaining the characteristic properties of FRP materials for use in structural design * The design of concrete structural members reinforced with FRP reinforcing bars * Design of FRP strengthening systems such as strips, sheets, and fabrics for upgrading the strength and ductility of reinforced concrete structural members * The design of trusses and frames made entirely of FRP structural profiles produced by the pultrusion process
