强度折减系数 meaning in English
strength reduction factor
Examples
- The influence on the shear resistance of columns by the axial loads includes two aspects : the one is that the axial load enhances the concrete strength of column in the inclined compression zone and the other is that the axial load increase the stress of the concrete of column in the inclined compression zone so that the shear resistance of column turns down
考虑轴力对柱抗剪承载力的影响，主要体现在轴力对斜压带混凝土强度折减系数提高的有利影响和轴力增加了斜压带混凝土的应力从而减少了柱的抗剪承载力的不利影响两方面，提出了考虑轴力影响的用于受剪的斜压带混凝土抗压强度f ~ ( - Using the model parameter from the dynamical experiment , the integrated parameters can be disassembled , thus the structure ' s frequency and the influencing coefficient of their oscillation mode are solved . it ' s tested from the model experiments and fem that the model given by the article has the virtue of explicit concept and convenient method and high accuracy , and it can give reference to evaluate the load capacity of bridge . in the end , in order to assess the existing bridge ' s seismic resistance performance , force reduction factor with ductility is recommended to reflect the seismic force of the structure during the elastic and plastic periods
另一方面，由动力相似理论建立了室内模型，并进行室内动力试验，借助量测到的模态参数分解出综合参数，可以反推结构频率及振型参与系数。试验结果、有限元计算值表明，本文建立的模型概念明确、计算方法简便、精度较高，可以为动测法评定桥梁结构承载力提供参考。最后，从延性的角度给出强度折减系数来考虑结构进入弹塑性阶段的地震力，从而对桥梁的抗震性能做出评价。 - In terms of strength and ductility , the concept of specified yield point is put forward . based on the principle that under the same condition ( that is , the size of cross section , material strength and reinforcement ratio are identical ) , the resultant ultimate moment must be identical , the compression failure of frp reinforced concrete beam is equal to the tension failure for the viewpoint of design and calculation
从强度与延性两方面的综合考虑，提出了纤维增强塑料筋名义屈服点的概念，对发生受压破坏的纤维增强塑料筋混凝土梁，按照同样条件下(截面尺寸、材料强度、截面配筋率等均相同)截面承载力相等的原则等效转化为受拉破坏进行设计与计算，以此确定纤维增强塑料筋的强度折减系数_ f 。 - An explicit formula of ultimate strength is achieved according as combination of elastic large deflection method and rigid plastic method for perfect plates . 2 . the explicit formulae with damage parameters as variable of reduction factors for ultimate strength of damaged plates are achieved by curve fitting based on a mass of numerical computation for parametric imperfection and damage of plates
