Download or read book Plastic Component Design written by Paul D. Q. Campbell and published by Industrial Press Inc.. This book was released on 1996 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is for the industrial designer interested in the applications of plastics in products and industry. It explains how different plastics are processed, and it contains extensive examples of common and unusual plastic components and products with an explanation of how they are manufactured. Every year, more products are being replaced or augmented by the same product made from plastic, and this trend has resulted in much debate about the effectiveness of plastic replacements. Today's plastics can be designed to operate in all weather conditions and chemical surroundings. They can be economically produced for short run part production or readily adapted to high quantity production, and they can be cut, glued, tapped, or machined by traditional methods to suit design needs. Explains how to choose the best processing method, what fastening or joining methods can be used, and how to use the characteristics of a plastic to judge its suitability for an application. Covers all major contemporary molding processes. Discusses, in detail, important topics such as surface finish and special effects.

Available in PDF, EPUB and Kindle. Book excerpt: Elastic, Plastic and Yield Design of Reinforced Structures presents a whole set of new results which have been published by the authors over the last 30 years in the field of continuum solid mechanics applied to the analysis and design of reinforced civil engineering structures. The focus is on the development and application of up-scaling/homogenization methods in the design of such composite structures, with a special emphasis on the plastic behavior and ultimate strength of materials. The specificity of the book is highlighted by at least two completely innovative concepts which lie at the very heart of the book’s originality: the elaboration of a fully comprehensive homogenization-based method for the design of reinforced structures (and not only materials), through the study of macroscopic behavior, and the development of a multiphase model for materials reinforced by linear inclusions, which considerably extends the range of applicability of the classical homogenization procedure. Sums up almost thirty years of original research in the field of mechanics applied to the analysis and design of reinforced civil engineering structures Focuses on the application of upscaling/homogenization methods to the design of civil engineering structures Highlights the elaboration of a fully comprehensive homogenization-based method for the design of reinforced structures (and not only materials), through the concept of macroscopic behavior Features development of a multiphase model for materials reinforced by linear inclusions, which considerably extends the range of applicability of the classical homogenization procedure.
Download or read book Performance Based Seismic Design for Tall Buildings written by Ramin Golesorkhi and published by . This book was released on 2017-10-30 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Performance-Based Seismic Design (PBSD) is a structural design methodology that has become more common in urban centers around the world, particularly for the design of high-rise buildings. The primary benefit of PBSD is that it substantiates exceptions to prescribed code requirements, such as height limits applied to specific structural systems, and allows project teams to demonstrate higher performance levels for structures during a seismic event.However, the methodology also involves significantly more effort in the analysis and design stages, with verification of building performance required at multiple seismic demand levels using Nonlinear Response History Analysis (NRHA). The design process also requires substantial knowledge of overall building performance and analytical modeling, in order to proportion and detail structural systems to meet specific performance objectives.This CTBUH Technical Guide provides structural engineers, developers, and contractors with a general understanding of the PBSD process by presenting case studies that demonstrate the issues commonly encountered when using the methodology, along with their corresponding solutions. The guide also provides references to the latest industry guidelines, as applied in the western United States, with the goal of disseminating these methods to an international audience for the advancement and expansion of PBSD principles worldwide.

Download or read book Performance based Plastic Design of Earthquake Resistant Steel Structures written by Mohammad Reza Bayat and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: It is well known that structures designed by current codes experience large inelastic deformations during major earthquakes. However, current seismic design practice in the U.S. is based on elastic structural behavior and accounts for inelastic behavior only in an indirect manner through certain modification factors such as R, I, and Cd. Under moderate to severe earthquakes, inelastic activity, including severe yielding and buckling of structural members can be unevenly distributed in the structure which may result in global collapse or costly repair work. Recently, a new design method has been developed and referred to as Performance-Based Plastic Design (PBPD). This method directly accounts for inelastic behavior by using pre-selected target drift and yield mechanism as key performance limit states. In this research work, the application of PBPD is successfully extended to design of mid-rise to tall steel Concentrically Braced Frames (CBF) with increased confidence level against collapse and also to tall steel Moment Frames (MF). The PBPD procedure for design of Steel Plate Shear Walls (SPSW) is also developed. The PBPD method is extended to design of mid-rise to tall CBF structures by proposing several key modifications in the calculation of design base shear. These include: consideration of column axial deformations in estimation of yield and target drifts, lateral force distribution to prevent large story drifts at upper stories due to higher mode effects, and target drift by proposed lambda-factor to account for pinched hysteretic behavior. Moreover, different methods are suggested to enhance the confidence level of mid- to high-rise CBF structures against collapse. These methods include: increase in design base shear by using slightly larger lambda-factor for mid- to high-rise frames, using Split-X configuration for braces, and increasing the minimum required fracture life, Nf. Application of PBPD method in design of tall MF structures is successfully carried out. Modifications for design of tall MF systems, primarily on design of columns, are proposed to achieve this goal. The current PBPD procedure for design of columns in steel MF structures works well for low-rise frames, but results in overdesigned sections for mid- to high-rise frames. It is shown that by applying the proposed modifications in design of tall MF, excellent seismic performance under pushover as well as time-history analyses can be achieved. The PBPD procedure for design of SPSW, an emerging lateral load resisting system, is developed. This procedure uses target drift and yield mechanism as key performance limit states. The pinched hysteretic behavior of SPSW is directly accounted for in this method by using the proposed lambda-factor method. By applying this method in the design of a 4-story SPSW frame, it was shown that the proposed PBPD procedure works very well for design of these systems. The performance criteria of target drifts and yield mechanisms were successfully met for the PBPD designs. In addition, with the proposed PBPD procedure, multiple level design based on appropriate target drifts for each hazard level, can be easily implemented. In general, the PBPD designed frames showed improved performance compared to the code designed SPSW frame, especially under MCE ground motions.

Download or read book Plastics Product Design Engineering Handbook written by Sidney Levy and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plastics have become increasingly important in the products used in our society, ranging from housing to packaging, transportation, business machines and especially in medicine and health products. Designing plastic parts for this wide range of uses has become a major activity for designers, architects, engineers, and others who are concerned with product development. Because plastics are unique materials with a broad range of proper ties they are adaptable to a variety of uses. The uniqueness of plastics stems from their physical characteristics which are as different from metals, glasses, and ceramics as these materials are different from each other. One major concern is the design of structures to take loads. Metals as well as the other materials are assumed to respond elastically and to recover completely their original shape after the load is removed. Based on this simple fact, extensive litera ture on applied mechanics of materials has been developed to enable designers to predict accurately the performance of structures under load. Many engineers depend on such texts as Timoshenko's Strength of Materials as a guide to the performance of structures. Using this as a guide, generations of engineers have designed economical and safe structural parts. Unfortunately, these design principles must be modified when designing with plastics since they do not respond elastically to stress and undergo permanent deformation with sus tained loading.
