解釋

At this background, though coupling beams with the small ratio of the span to depth have no sufficient test results, in order to satisfy the needs of engineering design, the code for design of reinforced concrete high - rise structure ( jgj3 - 2002 ) still adopt the design method of decreasing the maximum shear force and increasing the quantity of stirrups. but in china code for design of concrete structures ( gb 50010 - 2002 ) the content of seismic design methods for these kinds of coupling beams continue to be blank
在這一背景下， 《高層建築混凝土結構技術規程》 （ jgj3 - 2002 ）為了滿足工程設計需要，對小跨高比連梁在沒有充分試驗結果的情況下，仍採用降低最大作用剪力和提高箍筋用量的設計方法（雖然這種方法已被國外試驗證明在跨高比小於1 . 50的連梁中是肯定不能保證延性要求的） ，而《混凝土結構設計規范》 （ gb50010 - 2002 ）則把這部分內容繼續留作空缺。 -

本文通過對三根小跨高比（均為l h = 1 . 0 ）剪力墻洞口連系梁在低周反復荷載作用下的試驗，了解了嚴格按《鋼筋混凝土高層建築結構設計與施工規程》 （ 2000年徵求意見稿）設計的連梁具有的抗震性能，研究了採取增大連梁配箍量同時加強縱向構造筋的方案對抗震性能的影響，並進一步對新的配筋形式的連梁進行了探討，了解了在連梁梁端配置多排交叉斜筋方案對連梁抗震性能的改善。通過對試驗現象的觀察和量測結果的分析，利用荷載?位移滯回曲線、延性和耗能性能等指標對各個試件的抗震性能進行了比較，最後得出結論： 《鋼筋混凝土高層建築結構設計與施工規程》 （ 2000年徵求意見稿）不能保證小跨高比連梁具有較好的抗震延性：通過增大連梁配箍量同時加強縱向構造筋的方案對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較好的受力性能，其延性和耗能性能等各項性能指標均優于普通配筋連梁，宜在深連梁中採用。 -
From above analysis, the thesis gets conclusions as following : ( 1 ) the frequencies of multi - tower building are so dense and the coupling in each mode is so evident that the cqc method instead of srss should be used to calculate the seismic action effect ; ( 2 ) torsion effects is distinct between the modes of asymmetry multi - tower structure and it is necessary to take translation - torsion coupling into account ; ( 3 ) the effect of the enlarged base rigid on the seismic properties is very big, the rigid ratio of the enlarged base to towers in asymmetry multi - tower structure should be designed in a proper range ; ( 4 ) the distribution of plane rigid is asymmetry because of the asymmetry layout of towers. the torsion effects of structure not only result in large torsion internal force in vertical element resisting lateral displacement, but also make large influences on the stress of transfer plate and near floors, thus it is necessary to strengthen those floors
通過上述分析，得出以下主要結論：多塔樓結構存在頻率密集現象，各振型間耦聯效應明顯，地震作用計算應採用cqc組合原則而不能簡單地採用srss組合原則；非對稱多塔結構的振型中，扭轉作用明顯，平扭耦聯效應值得考慮；裙樓剛度對整體結構的抗震性能影響很大，非對稱多塔結構宜控制裙樓與塔樓剛度比在適宜的范圍；非對稱多塔易導致平面剛度分佈不均勻，結構扭轉效應不僅在豎向抗側構件中引起較大的扭轉內力，對轉換層樓板應力有較大的影響，且延續至相鄰樓層，對相應樓層均應採取相應的加強措施。 -
