【 摘 要 】

At present, the calculation of filler wall in building structure industry is usually implemented by the method of cycle reduction. However, the empirical coefficient proposed by the cycle reduction in view of standard is not accurate. The factors such as the number of filler walls and the rate of opening holes in the structure have different effects on the stress of the structure. Because the stiffness degradation of filler wall is different at different floors and under different stress conditions, the determination of equivalent diagonal bracing width is more complicated. It has been a controversial issue that how the new damping filler wall in the industry to establish an effective formula for calculating the cross-section width of equivalent diagonal brace to be applied to the elastic calculation of the first stage of the seismic and the elastic-plastic calculation of the second stage of the seismic in the case of large earthquakes.
