endurance time (et) method is a relatively new performance-based earthquake method for structural evaluation and design. in this method, the structure is subjected to a gradually intensifying accelorogram(s) and its performance is assessed based on the maximum time duration that it can meet the specified performance objectives. using moment-resisting and braced frames which are rehabilitated by...

many old damaged and undamaged building structures do not meet the criteria of modern seismic design codes. such structures need to be seismically enhanced. the main objective of this paper is to propose and validate the effectiveness of an upgrade scheme for non-seismic buildings using steel plate shear walls (spsw). the upgrade is carried out considering a probability-based drift-based criter...

The aim of this study was to examine the effect of inherent and incremental ability theories feedback on dynamic balance in middle-aged women. 29 middle-aged women (age: 50-60) randomly assigned into two groups (inherent ability= 15 subjects, and incremental ability= 14 subjects). Both groups after the dynamic balance pretest (Timed Up and Go) received different instructions feedback. Immediate...

The seismic response assessment of rocking systems via Incremental Dynamic Analysis (IDA) is investigated, focusing on the issues that arise in analysis and postprocessing stages. Rocking IDA curves generally differ from those hysteretic structural due to (i) frequent appearance resurrections; (ii) their highly weaving non-monotonic behavior; (iii) overall high variability. Hence, including or ...

زلزله به عنوان یک پدیده طبیعی ویرانگر است که هر ساله قسمتی از زمین را می لرزاند و خرابی به بار می آورد. جهت کاهش این خسارت، احداث ساختمان های مقاوم در برابر زلزله و بهسازی ساختمان های موجود لازم بوده و برای رسیدن به این هدف، آگاهی از چگونگی رفتار سازه های موجود ضروری است. تحلیل دینامیکی افزایشی (incremental dynamic analysis) روشی است که اخیراً مورد توجه قرار گرفته و می تواند رفتار سازه را با افز...

Incremental dynamic analysis (IDA) requires the analysis of the non-linear response history of a structure for an ensemble of ground motions, each scaled to multiple levels of intensity and selected to cover the entire range of structural response. Recognizing that IDA of practical structures is computationally demanding, an approximate procedure based on the reduction of the number of ground m...

The incremental dynamic analysis is a powerful tool for evaluating the seismic vulnerability and risk of buildings. It allows calculating the global damage of structures for different PGAs and representing this result by means of damage curves. Such curves are used by many methods to obtain seismic risk scenarios at urban level. Even if the use of this method in a probabilistic environment requ...

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 Dam...
