طراحی ساختمان های بلند پیچیدگی های مخصوص به خود را دارد. برای غلبه بر این پیچیدگی ها سیستم های سازه ای متفاوت برای کنترل تغییر مکان جانبی در ساختمان های بلند ابداع شده اند. یکی از این سیستم ها سیستم مهار بازویی است که تغییر مکان جانبی سازه و لنگر فونداسیون سازه را کاهش می دهند. موقعیت مهار بازویی تاثیر بسزایی بر روی کارایی سازه دارد. یکی از مسائل اساسی تعیین موقعیت مهار بازویی در ساختمان های بل...
This article outlines a new approach to rapidly estimate the damage to tall buildings immediately following a large earthquake. The preevent groundwork involves the creation of a database of structural responses to a suite of idealized ground-motion waveforms. The postevent action involves (1) rapid generation of an earthquake source model, (2) near real-time simulation of the earthquake using ...
The main objectives of the research are to characterize the wind-induced resonant and slowly-varying (quasi-static) responses of a tall building under ambient wind excitations based on GPS measurements. The equipment used includes two sets of orthogonally aligned accelerometers, two GPS receivers and an ultrasonic anemometer. The natural frequencies of the wind-induced vibration of the tall bui...

In this paper, an efficient technique is presented for static analysis of tall buildings with combined tube-in-tube and outrigger-belt truss system while considering shear lag effects. In the process of replacing the discrete structure with an elastically equivalent continuous one, the structure is modeled as two parallel cantilevered flexural-shear beams that are constrained at the outrigger-b...
Summary In this study, the seismic performance of hexagrid structures which are composed of horizontal and vertical hexagrid by using a transitional story, has been investigated. To this end, 10 models of 50-story hexagrid structures were designed. 9 models with horizontal hexagrid cells which transited to vertical cells using a transitional story, and a model of completely horizontal hexagrid ...
