Assessment of an RC existing hospital building with special moment frame using fragility curve
Authors
Abstract:
In this study, an existing hospital structure has been evaluated with incremental dynamic analysis (IDA). This building is accommodated in Karaj with soil type II. At first, two 2-D frames along X, Y direction are selected. Then, five performance levels are determined according to “Rehabilitation Code for Existing Buildings (Publication No. 360) including Immediate Operational (IO), Limited Damage (LD), Life Safety (LS), Limited Life Safety (LLS), and Collapse Prevention (CP). The Peak Ground Acceleration (PGA) as earthquake intensity and relative displacement (Drift) as the failure index has been used for incremental dynamic analysis method via seismo-struct software. In the next step, the probability of reaching or exceeding of the structure to a limit state was determined. Results of incremental dynamic analysis for fragility curves show that the probability of reaching or exceeding from IO level is approximately . This probability is almost for LD, for LS, for LLS, and for CP. It has been signified that the probability of fragility is raised with increasing in PGA

Seismic fragility assessment of RC moment resisting frame buildings designed for different editions of Iranian seismic design code
Background and objective: Developing fragility and vulnerability functions are important tools in seismic reliability assessment of buildings and are widely used in regional seismic risk studies. To date sufficient studies for developing analytical fragility functions for Iranian code-conforming buildings have not been carried out. Performing such studies are necessary to assess the adequacy of...

Fragility curves represent the probabilities that structural damages, under various levels of seismic excitation, will exceed the specified damage states by means of earthquake intensity damage relations. Conceptual aspects related to seismic vulnerability, damage and risk evaluation are discussed first, together with a short review of the most widely used possibilities for the seismic evaluati...

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 ...
