- In this paper , a new ductile rc coupled shear wall , namely rc coupled shear wall with concealed bracings , was put forward based on the study of shear wall with concealed bracings and inclined across steel bars in lintel beam . then the seismic design methods on shear wall with concealed bracings was given through the experimental study and theoretical analysis on seismic behavior and corresponding finite element analysis on elastic - plastic

通过试验和理论分析证明了在连梁中加配交叉斜筋对提高承载力和延性效果显著，两墙肢加设暗支撑后，两墙肢抗震能力明显加强，同时结构整体变形和耗能能力显著增强，带暗支撑双肢剪力墙的关键在于合理地控制了剪力墙的破坏机制。 - 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
本文通过对三根小跨高比(均为l h = 1 . 0 )剪力墙洞口连系梁在低周反复荷载作用下的试验，了解了严格按《钢筋混凝土高层建筑结构设计与施工规程》 ( 2000年征求意见稿)设计的连梁具有的抗震性能，研究了采取增大连梁配箍量同时加强纵向构造筋的方案对抗震性能的影响，并进一步对新的配筋形式的连梁进行了探讨，了解了在连梁梁端配置多排交叉斜筋方案对连梁抗震性能的改善。通过对试验现象的观察和量测结果的分析，利用荷载?位移滞回曲线、延性和耗能性能等指标对各个试件的抗震性能进行了比较，最后得出结论： 《钢筋混凝土高层建筑结构设计与施工规程》 ( 2000年征求意见稿)不能保证小跨高比连梁具有较好的抗震延性：通过增大连梁配箍量同时加强纵向构造筋的方案对改善连梁的抗震延性的效果不太明显；梁端配置多排交叉斜筋的连梁具有相对较好的受力性能，其延性和耗能性能等各项性能指标均优于普通配筋连梁，宜在深连梁中采用。 - The long period cyclic tests of four specimens near to sufficient dimension made by the master cao yunfeng prove that the reinforcement arrangement scheme can obtain favorable displacement ductility and plastic energy dissipation capacity for the coupling beams with the small aspect ratio of 1 . 0 . to go deep into the research further , this thesis concentrates on the two aspects following : ( 1 ) the author of this thesis carries out the long period cyclic test of five specimens near to sufficient dimension to further verify : 1 ) the probability that the upper limit of shear - resistant ability increases to vu = 0 . 2fcbh0 or higher
0的位移延性，且耗能能力良好:在跨高比为0 . 8一1 . 25的范围内，连梁都依然保持上述良好性能;配筋比例应以对角斜筋为主，一组“ l ”形斜筋用量与单向对角斜筋用量的比值宜控制在0 . 35一0 . 55的范围内;通过对曹云峰的试验与本文试验的综合分析，表明cz于c45的混凝土强度等级都是可用的，未发现混凝土强度在这一范围内偏高或偏低时可能带来什么不利影响。 - To guarantee the stability of the frame in strong earthquake motion , and on the basis of analysis on the concept of “ capacity design ” in the above three countries seismic design provisions , it is advised that the moment amplification coefficients at the bottom sections of columns for the frame structures in some seismic intensity be increased to reduce the possibility of the frame column yielding . taking the above three countries seismic codes as reference , it is recommended that it be added details of seismic design by using diagonal shear reinforcement to safeguard beams against sliding shear failure , when the positive - negative shear forces are reverse and the ratio is high
为了保证在大震作用下框架结构的稳定性,借鉴国外规范“柱-梁承载力级差系数”的思想,本文提出了对部分抗震等级的框架结构的柱端抗弯能力增强系数应予以提高,以降低框架柱屈服的可能性;参照国外有关规范的发展,本文建议对于正、负剪力反向且比值较大的框架梁宜增加交叉斜筋,以防止沿垂直裂缝发生严重的剪切错动。
