Numerical evaluation of the reliability of using single-story substructures to study progressive collapse behaviour of multi-story RC frames

چکیده
Progressive collapse is a global failure for multi-story building. All stories above the removed column will consequently deform and help redistribute loads initially withstood by column. However, due to cost excessive time be involved, majority of existing experimental researches regarding progressive rely on single-story beam-column substructures or sub-assemblages. To date, how use results from sub-assemblages fully confidently study behavior building still unclear. Thus, it imperative investigate relationship between real buildings. this purpose, in present study, series planar reinforced concrete (RC) were modeled using high-fidelity finite element software LS-DYNA. Firstly, numerical models validated test two three-story with different design spans. Secondly, explored various load resistance each story investigated frame. In addition, effects boundary conditions, missing locations, numbers variation studied detail models.

Evaluation of the Seismic Response of Single-Story RC Frames under Biaxial Earthquake Excitations
This paper summarizes the lessons learned from a full-scale test on two RC frame prototypes that have recently been tested on LNEC shaking-table using four pairs of biaxial synthetic ground motion records during 15WCEE Conference (2012). The reference structures are two single-story RC frames which are geometrically identical but with different reinforcement details. The simplified inelastic mo...

چکیده هدف اصلی از طراحی لرزه ای تامین ایمنی جانی در هنگام وقوع زلزله و تعمیر پذیر بودن سازه خسارت دیده، پس از وقوع زلزله است. تجربه زلزله های اخیر نشان داده است که ساختمان های طراحی شده با آیین نامه های مبتنی بر نیرو از نظر محدود نمودن خسارت وارده بر سازه دقت لازم را ندارند. این امر سبب پیدایش نسل جدید آیین نامه های مبتنی بر عملکرد شده است. در این آیین نامه ها بر اساس تغییرشکل های غیرارتجاعی ...
