發(fā)布時(shí)間:2018-11-18 18:58
【摘要】:設(shè)計(jì)不同柱梁抗彎承載力比(ηc-bua)的5個(gè)纖維增強(qiáng)混凝土(FRC)框架結(jié)構(gòu)及3個(gè)鋼筋混凝土(RC)框架結(jié)構(gòu),利用性能評估軟件Perform-3D進(jìn)行Pushover及IDA計(jì)算分析,得出其破壞機(jī)制及易損性曲線。結(jié)果表明,柱、梁端部局部采用FRC后,承載力有一定提高,峰值位移有較大提高;ηc-bua對FRC框架結(jié)構(gòu)的破壞機(jī)制影響很大;ηc-bua對FRC框架結(jié)構(gòu)地震反應(yīng)也有一定的影響,其比值越大,超越概率越小,且隨期望破壞程度的加重,這種影響也趨于明顯,當(dāng)ηc-bua在1.2以上時(shí),結(jié)構(gòu)的倒塌概率均小于10%,滿足大震不倒的概率要求。
[Abstract]:Five fiber reinforced concrete (FRC) frame structures and three reinforced concrete (RC) frame structures with different ratio of flexural bearing capacity (畏 c-bua) of column beams were designed. Pushover and IDA were calculated and analyzed by using the performance evaluation software Perform-3D. The failure mechanism and vulnerability curve are obtained. The results show that the bearing capacity and peak displacement of column and beam end are improved by using FRC, and 畏 c-bua has great influence on the failure mechanism of FRC frame structure. 畏 c-bua also has a certain influence on the seismic response of FRC frame structure. The larger the ratio, the smaller the transcendental probability, and with the increase of expected damage degree, the effect tends to be obvious, when 畏 c-bua is above 1.2, The collapse probability of the structure is less than 10.
