Seismic analysis of a modern 14?story reinforced concrete core wall building system using the BTM?shell methodology

This paper uses computational simulation to investigate the lateral load-displacement behavior and failure modes of a modern 14-story reinforced concrete (RC) core wall building. The design complies with minimum code requirements current California Building Code, which is based on ASCE 7–16 ACI 318–14. representation building, accounts for material nonlinearities all structural components, employs beam-truss model (BTM) walls floor slabs. Analyses building are conducted static monotonic cyclic loads using program FE-MultiPhys, provides user-friendly implementation BTM as an assemblage rectangular shell macroelements. Two different load patterns, that is, distributions along height, considered. analyses provide insights into evolution damage strength degradation their dependence pattern, while also elucidating complex interaction between webs flanges system effects associated coupling walls, beams, slabs, columns. presentation analytical results accompanied by discussion advantages over seismic analysis methods used in code-minimum performance-based (PBSD) practice.
