Finite element simulate analysis of small span - to depth ratio coupling beams with special reiforcement 特殊配筋小跨高比洞口连梁的有限元模拟
Coupling beams " failure mode , shear distortion , ductility and energy dissipation were impacted by different shear - compression ratio from 0 . 15 to 0 . 20 是一种值得推荐的抗震联肢墙小跨高比洞口连梁的配筋形式。
Aiming at this important problem to be urgently settled in engineering design , the research group in which the author of this thesis is have carried out a series of test investigations on coupling beams with small aspect ratio 针对工程设计中这一急待解决的重要问题，本论文作者所在的研究组对小跨高比连梁进行了系列试验研究。
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 由于建筑构造，常有可能出现跨高比较小的洞口连梁，连梁在地震作用下会同时受到很大弯矩与剪力，其受力状态十分复杂。
So far domestic and foreign researches have not yet found out an effective reinforcement arrangement scheme for convenient construction and guaranteeing the occurrence of shear failure after coupling beams attaining displacement ductility required 至今国内外仍未找到一种既方便施工，又能保证剪切失效出现在连梁达到所需的位移延性之后的有效配筋方案。
However , for small span - to - depth ratio coupling beams are counter flexural deep beams restrained at their two ends and points of contraflexure at the center of the span , the rules of their carrying forces and deformation are not like common deep beams 但是，小跨高比连梁属于两端被约束，反弯点在跨中的反对称弯曲深梁，其受力和变形规律不同于一般深梁。
Based on the conclusion of the test , we discussed the ductility of hollow shear wall r . c . structure and effect of the coupling beams . in accordance with the code and other tests , the advice of the detailing of hollow shear wall r . c 并在对试验结果进行综合分析的基础上，讨论了空心剪力墙结构的延性及连梁所起的作用；参照相关规范和其他试验，对空心剪力墙结构的设计构造提出建议。
In china code for design of concrete structures ( gb 50010 - 2002 ) , there are no design methods for coupling beams when the depth - to - span ratio is less than 2 . 5 , which is one of the critical problems of the code for design of concrete structures unsolved 并且新颁布的《混凝土结构设计规范》 （ gb50010 ? 2002 ）也没有针对跨高比不大于2 . 5的连梁提出具体的设计方法，小跨高比连梁的设计仍是有待通过试验研究来澄清的问题之一。
Coupled walls include two or more single shear walls connected by coupling beams , which are the first line of energy dissipation under earthquake . so coupling beams " strength , stiffness , ductility and energy dissipating capacity can effect shear walls " performance directly 联肢剪力墙通过连梁把单片剪力墙连接在一起，是延性剪力墙抗震的第一道防线，因而连梁的强度、刚度、延性及耗能能力直接影响着剪力墙的性能。
