Nonlinear modeling of the ten-story RC building at E-Defense (2015): assessment with different modeling assumptions

Abstract Two models of the 10-story reinforced concrete building tested at E-Defense laboratory in 2015 are built: F model, which nonlinear behavior is distributed over element length, and H lumped plastic hinges with a moment-chord rotation response assigned based on empirical formulations proposed literature. Nonlinear time–history analyses performed to reproduce experimental shaking-table tests increasing seismic intensity level. The incremental test has been twice: first time (BS test), structure base was free slip fixed shaking table. After BS test, second same foundation (BF test). Both simulated for both models. When simulating BF tests, input adopted numerical displacement time-history registered specimen’s columns, order implicitly account through signal without explicitly modeling slipping devices. It observed that significant damage experienced by specimen during runs medium–high probably triggered softening beam-column joints: this reproduced also model highlights influence joints overall structure. In general, it models, were constructed, data, only adopting available well-established tools literature, can case-study structure, especially terms maximum top demand state structural members, provided joints’ contribution adequately considered.
