支腿系統(tǒng)是一種有效的結(jié)構(gòu)方案,常用於高層建築中,以提高剛度,並將所需的力矩分配到外柱上。儘管世界各地都在使用支腿結(jié)構(gòu)系統(tǒng),但還是缺少一個(gè)正式的地震設(shè)計(jì)程式。本文提出了一種等效的基於能量的設(shè)計(jì)過程（EEDP）來設(shè)計(jì)地震應(yīng)用的支腿系統(tǒng)。利用能量平衡的概念,將彈性單自由度系統(tǒng)等同于等效非線性系統(tǒng),利用塑性機(jī)制推匯出支腿系統(tǒng)的設(shè)計(jì)力。等效的基於能量的設(shè)計(jì)程式（EEDP）允許工程師設(shè)計(jì)的支腿牆建築,以達(dá)到不同的性能目標(biāo),在不同的地震危險(xiǎn)性水準(zhǔn),這是理想的創(chuàng)造地震彈性的建築物。在加拿大溫哥華的一個(gè)假想網(wǎng)站上,設(shè)計(jì)了三個(gè)不同高度的模型式支腿牆建築。利用OpenSees對原型建築物的抗震性能進(jìn)行了詳細(xì)的有限元模型研究。非線性時(shí)間歷史分析結(jié)果表明,該原型能夠滿足設(shè)計(jì)過程中指定的性能目標(biāo)。最後,利用聯(lián)邦應(yīng)急管理局P695方法對基於等效能量設(shè)計(jì)程式（EEDP）設(shè)計(jì)的支腿系統(tǒng)的抗震安全性進(jìn)行了增量動態(tài)分析。結(jié)果表明,所提出的等效能量設(shè)計(jì)過程（EEDP）是設(shè)計(jì)支腿系統(tǒng)的一種有效方法,在該結(jié)構(gòu)中可以達(dá)到足夠的安全裕度以防止坍塌,滿足多個(gè)性能目標(biāo)。不帶反覆運(yùn)算的不同危險(xiǎn)級別。
