Effect of seismic sequences on fragility of Iranian code-conforming shear wall RC buildings
Background and objective: Estimating the vulnerability rate of urban textures in seismic incident following a major earthquake (aftershocks) is crucial in decision making and crisis management. For this purpose, it is necessary to calculate the vulnerability of buildings due to the successive incidents and to use them in the vulnerability estimation for probable future aftershocks. Seismic frag...
متن کاملassessment of the park- ang damage index for performance levels of rc moment resisting frames
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 ...
15 صفحه اولApplication of a recently proposed displacement-based assessment procedure for asymmetric-plan RC wall buildings
Architectural layouts of reinforced concrete buildings often require structural walls, with varying dimensions, to be placed in an asymmetric plan configuration. During seismic excitation the asymmetry induces a torsional component of response, which can impact negatively on the performance of the building by increasing demands on both structural and nonstructural elements. Furthermore, the tor...
متن کاملEvaluation of seismic assessment procedures for determining deformation demands in RC wall buildings
This work evaluates the performance of a number of seismic assessment procedures when applied to a case study reinforced concrete (RC) wall building. The performance of each procedure is evaluated through its ability to accurately predict deformation demands, specifically, roof displacement, inter-storey drift ratio and wall curvatures are considered as the key engineering demand parameters. Th...
متن کاملLimiting Fiber Extensibility as Parameter for Damage in Venous Wall
An inflation–extension test with human vena cava inferior was performed with the aim to fit a material model. The vein was modeled as a thick–walled tube loaded by internal pressure and axial force. The material was assumed to be an incompressible hyperelastic fiber reinforced continuum. Fibers are supposed to be arranged in two families of anti–symmetric helices. Considered anisotropy correspo...
