The method applied two elements to analyze the collapse mechanism and hysteretic behavior of eccentrically braced steel frames under cyclic load in structure at first time 在整體結(jié)構(gòu)中采用兩種單元較精確的分析偏心支撐鋼框架的滯洄性能及破壞機(jī)理的方法,在國內(nèi)外均屬首次。
This p aper aim at the project application , study on collapse mechanism and design criteria of eccentrically braced steel frames under cyclic load 本文以工程應(yīng)用為目的,研究和探索了各種典型的偏心支撐鋼框架在循環(huán)荷載作用下的滯洄性能和破壞機(jī)理,并提出了抗震設(shè)計(jì)對策和建議。
So , the analysis about response and collapse mechanism of ebfs under seismic loading are not only significant in theoretical aspect , but also important in practice 因此,分析偏心支撐框架在地震作用下的響應(yīng)以及提出改善耗能梁段的建議,不僅具有理論意義,而且具有很大的應(yīng)用價(jià)值。
And now , we use the reliability assessment standard to grade the buildings , and based on it , collapse mechanism method , fuzziness ensemble judge method come into use 發(fā)展到今天,多通過可靠性鑒定標(biāo)準(zhǔn)對建筑物進(jìn)行可靠性鑒定評(píng)級(jí),在此基礎(chǔ)上發(fā)展起來的有破損機(jī)構(gòu)法、模糊性綜合評(píng)判等方法。
It is complex nonlinear mechanism process . now the collapse mechanism of structure has not been clear , which has been a key project for earthquake researcher and civil engineer worker 至今人們對結(jié)構(gòu)在地震力作用下的倒塌破壞機(jī)理都不是很清楚,這歷來一直是地震工作者和土木工作者研究的重要課題。
