Nonlinear Dynamic Analyses Utilising Macro-Models of Reinforced Concrete Building Structures and Site-Specific Accelerograms

This paper aims to guide structural engineers on how apply the rapid nonlinear time history analysis (RNLTHA) procedure effectively predict seismic demand, taking into account ductility and overstrength, effects of dynamic phenomena including cyclic degradation strength stiffness in structures, a direct expedient manner. The shortcoming conventional force-based approach design involving use force reduction factor for is well recognised. Nonlinear static (pushover) (NLTHA) are offered as alternative methods by major codes practices achieve better optimisation materials. NLTHA has advantages over pushover being more capable capturing response behaviour. Despite merits NLTHA, its adoption industry been limited, mainly because complexity higher cost involved. RNLTHA proposed this article uses macroscopic model building fulfil purpose whilst saving computational achieving good degree accuracy, verified comparison with results generated from SeismoStruct.
