弯矩调幅系数 meaning in English
moment modified factor
monitor frame
Examples
- Moment modified factor
弯矩调幅系数 - ( 3 ) total coefficient of modulation of moment for the frame applied horizontal load and vertical load is bigger than that of the same frame applied vertical load
( 3 )框架既承受水平荷载又承受竖向荷载时的总弯矩调幅系数比相同结构只承受竖向荷载的总弯矩调幅系数大。 - Then limiting load is decreased . ( 6 ) horizontal load can increase the coefficients of the modulation of moment when value of is little while decrease it when is large
( 6 )在中支座截面相对受压区高度较小时，有水平荷载的框架其弯矩调幅系数要大于只有竖向荷载的框架。 - So , for the design of prestressed frame , the later coefficient may be considered as the parameter of modulation of moment and the moment modulated is the moment caused by the vertical load plus the one by the horizontal load
因此，在预应力框架设计中，可以取只承受竖向荷载的弯矩调幅作为其调幅标准，调幅弯矩为竖向荷载产生的弯矩与水平荷载产生的弯矩之和，即用最小的弯矩调幅系数来调整截面的弯矩。 - At last , with the program , 18 one - storey and one - span prestressed frames are simulated . some conclusions are reached with the taking into account the , secondary moment and types of load applying : ( 1 ) the in the beam affects the ductility of the section and rotary property of the plastic hinge . so total coefficient of the modulation of moment becomes less with the becoming bigger
最后，本文利用编制的非线性程序，模拟了18榀单层单跨预应力框架，重点研究截面相对受压区高度、次弯矩、加载方式对塑性内力重分布和弯矩调幅的影响，从中得出了以下主要的结论和规律： ( 1 )框架梁相对受压区高度在很大程度上反映了截面的延性，体现了塑性铰的转动能力，框架的总弯矩调幅系数随着相对受压区高度的增大而减小。
