assessment 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 اولDamage Assessment in Glass Fiber-Epoxy Matrix Composite under High Velocity Impact of Ice
This study investigated the influence of nanoclay on the impact damage resistance of glass fiber-epoxy composites under high velocity ice impact loading. Addition of 0.5 wt. % nanoclay into epoxy was shown to improve damage resistance compared to composite plates having no nanoclay platelet. The glass fiber-epoxy composites containing nanoclay brought about substantial improvement in ice impact...
متن کاملBlast Analysis of Laminated Glass Curtain Walls Equipped
Nonlinear numerical simulations are reported for a conventional unitized laminated glass curtain wall subjected to highand low-level air blast loading. The studied curtain wall, spanning floor to floor, consisted of a laminated glass panel, a continuous bead of structural silicone sealant, a split screw spline frame and four rigid brackets. Firstly, a linear elastic FE-model (M01) is presented ...
متن کاملAutomation System for Curtain Wall Installation Ii ( Asci Ii )
As a trial of automation for a curtain wall which is one of heavy materials, the prototype of an ASCI(Automation System for Curtain wall Installation) was proposed and applied in real construction site. Human-robot cooperation is one of the solutions to improve ASCI. The aim of this paper is to develop a control algorithm for ASCI, which is a human-robot cooperative system, and the practical ap...
متن کاملA damage-tolerant glass.
Owing to a lack of microstructure, glassy materials are inherently strong but brittle, and often demonstrate extreme sensitivity to flaws. Accordingly, their macroscopic failure is often not initiated by plastic yielding, and almost always terminated by brittle fracture. Unlike conventional brittle glasses, metallic glasses are generally capable of limited plastic yielding by shear-band sliding...
