Then the coupling beams with new reinforcement layout were made an inquiry into, and the improvement on the seismic behavior by coupling beams diagonally reinforced with a few rows in end regions was found out at last, based on the observations of the experimental phenomena and the analysis of the measurement result, and by the comparison of seismic behavior by making use of hysteretic response, ductility and energy dissipation behavior, a conclusion is presented : the code for design and construction of reinforced concrete high-rise structures ( the draft asked for advise hi 2000 ) ca n't ensure that the coupling beams have fairly good seismic ductility; the result of improvement of the seismic ductility of the coupling beams by the increase hi stirrups besides the strengthen of longitudinal detailing reinforcement was n't obvious; the coupling beams diagonally reinforced with a few rows in end regions have fairly good mechanisms, and the ductility and the behavior of energy dissipation are better than conventionally reinforced concrete coupling beams, so it is suitable to te tised in short coupling beams 本文通過(guò)對(duì)三根小跨高比(均為lh=1.0)剪力墻洞口連系梁在低周反復(fù)荷載作用下的試驗(yàn),了解了嚴(yán)格按《鋼筋混凝土高層建筑結(jié)構(gòu)設(shè)計(jì)與施工規(guī)程》(2000年征求意見(jiàn)稿)設(shè)計(jì)的連梁具有的抗震性能,研究了采取增大連梁配箍量同時(shí)加強(qiáng)縱向構(gòu)造筋的方案對(duì)抗震性能的影響,并進(jìn)一步對(duì)新的配筋形式的連梁進(jìn)行了探討,了解了在連梁梁端配置多排交叉斜筋方案對(duì)連梁抗震性能的改善。通過(guò)對(duì)試驗(yàn)現(xiàn)象的觀察和量測(cè)結(jié)果的分析,利用荷載?位移滯回曲線、延性和耗能性能等指標(biāo)對(duì)各個(gè)試件的抗震性能進(jìn)行了比較,最后得出結(jié)論:《鋼筋混凝土高層建筑結(jié)構(gòu)設(shè)計(jì)與施工規(guī)程》(2000年征求意見(jiàn)稿)不能保證小跨高比連梁具有較好的抗震延性:通過(guò)增大連梁配箍量同時(shí)加強(qiáng)縱向構(gòu)造筋的方案對(duì)改善連梁的抗震延性的效果不太明顯;梁端配置多排交叉斜筋的連梁具有相對(duì)較好的受力性能,其延性和耗能性能等各項(xiàng)性能指標(biāo)均優(yōu)于普通配筋連梁,宜在深連梁中采用。
