混凝土剪力墙连梁的设计计算及超筋处理(国外英文资料) Hundreds of BBS structure. Technical communication in March 2007 The design calculation of the concrete shear wall and the overreinforcement of the beam Zhu Bingyin (Beijing 100044, China institute of architecture design) 3 In the structure of shear wall and frame - shear wall structure, the girder in the structure of the shear wall and the structure of the frame tube are generally more prone to the phenomenon of hyperreinforcement, and the appropriate treatment method should be taken. Discussed in this article is under the condition of the structure is reasonable, while some still super steel coupling beam shear wall, designed according to the concrete high rules regulations in article 7.2.25 method to deal with properly. The calculation method of the beam 1.1.1 beam modulation processing (calculation result) The bending moment and shear force of the beam in the shear wall of aseismic design can be adjusted to reduce the design value of shear force. But in the structural calculation, the stiffness of the beam has been reduced, and the amplitude of the adjustment should be limited or no longer amplitude modulation. The bending moment of the beam and wall of the rest of the beam should be increased accordingly. In general, all the amplitude modulation (including the calculation of the beam stiffness reduction and the results of amplitude modulation) late after bending moment design value should not be less than 0.8 times of am (completely elastic) before (6, 7 degrees) and 0.5 (8, 9 degrees Fahrenheit). Note: 1) the adjustment method considering the tie-beam plastic internal force redistribution, effect of the coupling beam across high bigger is better, and to the relatively small across high coupling beam effect is poorer; The adjustment will ensure that the beam has no obvious effect on the vertical load. 1.2 link processing (calculation results) The destruction of the coupling beam when had no obvious effect on under vertical load (i.e.
