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。Coupling beams between openings are the main plastic energy dissipation elements of coupled walls, but whether short coupling beams could ensure that shear failure would n ' t take place before coupling beams have reached certain displacement ductility or not, is still a problem of engineering which has n ' t been solved and is one of the critical problem of the code for design of concrete structures which remains to be solved
洞口連系梁是聯肢剪力墻的主要塑性耗能構件，但跨高比較小的連梁是否能保證在達到一定的位移延性之前不出現剪切失效，仍是目前我國工程界未解決好的問題，也是我國《混凝土結構設計規范》遺留下來有待解決的關鍵問題之一。For three - short - pier shear wall under vertical loads, the results remain the same, and transfer beam at this moment will work with the middle pier, constituting a t - shape beam to sustain the moment and axial tensions together. 4. under the horizontal loads, the inner stress distribution in the frame supported short - pier shear wall shows similarities with that of the short - pier shear wall underneath the fastened supports
4 、水平荷載作用下，框支短肢剪力墻墻肢內的應力分佈形式接近於下部固支的短肢剪力墻的應力分佈;轉換梁承受上部墻肢傳遞的拉力、剪力和彎矩，當短肢剪力墻墻肢數量較多時，轉換樑上、下邊緣拉、壓應力交替出現，剪應力的最大值處于洞口下方的轉換梁體內。For the purpose of the architecture, sometimes depth - to - span ratio of coupling beams is very little, so coupling beams are subjected to great moment and shear, and distribution of stress and strain is very complex
由於建築構造，常有可能出現跨高比較小的洞口連梁，連梁在地震作用下會同時受到很大彎矩與剪力，其受力狀態十分復雜。In the new algorithm, spherical surface window is discussed and 3 - d line is divided into two kinds according to comparing the distance from sphere center to line with the radius of sphere
然後，本文首次提出了三維空間球面窗口的線裁剪演算法，對球面窗口進行了深入的研究，根據球心到三維線段的距離與球半徑的比較，將被裁三維線段分成兩大類進行處理。Taking account of the two aspects, the concrete strength " fc " in the inclined compression zone which contributes to the shear capacity of columns is put forward
利用修正的桁架+拱抗剪機理，提出了柱的抗剪承載力理論公式，與試驗數據比較表西安建築科技大學碩士學位論文頤口.面.分享友人
