底部剪力 meaning in Chinese
base shear
bottom shear
Examples
- The interfacial shear stress is a constant proportion of the bottom shear .
交界面的剪力与底部剪力之比是常数。 - The result of the new method has higher precision than that of the former . this method can be applied to the framed structures whose rigidities do not distribute equally along their heights
这种新的简化方法不仅精度比规范中的底部剪力法高，而且也适用于计算刚度沿高度分布不均匀的框架结构。 - Shear wall will bear mostly part of horizontal force . in this case , it can satisfy the limitation of displacement , and can be insure that the bottom shear force , natural vibration period of structure and the displacement curve can be novel . furthermore , it can supply good base for proceeding design
在合理的布置下，剪力墙承担大部分水平力，使结构满足侧移限值，并使结构的底部剪力，自振周期及侧移曲线不发生异常，并为以后的工作打下良好的基础。 - Secondly , the push - over analysis is for the three - dimensional solid element model and the plane beam element model . the total shearing force - lateral displacement curve can be obtained from it . and then the total shearing force - lateral displacement curve is converted to pseudo acceleration - period curve and some comparisons are made between the pseudo acceleration - period curve and design response spectrum
然后，建立了有限元三维实体单元模型及平面杆单元模型，对其进行了push - over分析，并将所得的底部剪力一顶点位移曲线转化为拟加速度一周期曲线，与规范反应谱进行对比，以此评定该体系的抗震能力。 - According to the code for aseismatic design of building structure ( gbj11 - 89 ) , the seismic base - shear method has always been used to calculate the seismic response of building structures . in those structures , their weights and rigidities equally distribute along their heights which do not exceed 40m , and their deformations are mostly the shearing type ( when the structures " ratio of height and width are smaller than 4 )
我国《建筑抗震设计规范》 ( gbj11 ? 89 )中规定，对于重量和刚度沿高度分布比较均匀、高度不超过40m ，并以剪切变形为主(房屋高宽比小于4时)的结构，可采用近似计算法，即底部剪力法来计算其地震响应。
