Fifteen static and dynamic tests were conducted to measure the actual magnitude of the curvature of a plastic hinge and to correlate the angle of deformation with resistance for beams subjected to dynamic loads. The primary variables were the amount of compression reinforcement, the distance between the concentrated loads, and the rate of loading. The dynamic step loads ranged in magnitude from about 1.10 to 1.25 times the static yield load. The computed values of moment, curvature, and deflection at the onset of plastic hinging were less than the experimental values for both static and dynamic loadings. The 30% increase in beam resistance under dynamic loads agreed with the increase in yield strength of the coupon specimens subjected to rapid straining. Plastic hinging was similar in the static and dynamic beams loaded at mid-span. Crushing occurred at approximately the same deflection under both types of load. For the beams with a pure moment region, a dynamic load equal to approximately 1.1 times the static load caused crushing at mid-span before the plastic hinge had developed as completely as it did for static loading; thus, for dynamic loads, the deflections were lower at the onset of crushing than they were for static loads.

This design code for concrete structures is the result of a complete revision to the former Model Code 1978, which was produced jointly by CEB and FIP. The 1978 Model Code has had a considerable impact on the national design codes in many countries. In particular, it has been used extensively for the harmonisation of national design codes and as basic reference for Eurocode 2. The 1990 Model Code provides comprehensive guidance to the scientific and technical developments that have occurred over the past decade in the safety, analysis and design of concrete structures. It has already influenced the codification work that is being carried out both nationally and internationally and will continue so to do.

Emphasizes actual structural design, not analysis, of multistory buildings for seismic resistance. Strong emphasis is placed on specific detailing requirements for construction. Fundamental design principles are presented to create buildings that respond to a wide range of potential seismic forces, which are illustrated by numerous detailed examples. The discussion includes the design of reinforced concrete ductile frames, structural walls, dual systems, reinforced masonry structures, buildings with restricted ductility and foundation walls. In addition to the examples, full design calculations are given for three prototype structures.

Plastic Design of Steel Frames assesses the current status and future direction of computer-based analyses of inelastic strength and stability for direct frame design. It shows how design rules are used in practical frame design and provides an introduction to the second-order theory of inelastic frame design. The book includes two computer programs on a diskette: one for the first-order analyses and the other for the second-order plastic hinge analysis of planar frame design. The second-order program can be used to predict realistic strengths and stabilities of planar frames, thereby eliminating the tedious task of estimating factors for individual member capacity checks. Both programs include clear input instructions. The diskette also contains the Fortran source-code listing for the second-order plastic-hinge analysis, enabling the user to customize the program. The programs will run on an IBM PC-AT or equivalent machine with 640 kB of memory and 30 MB hard drive.
