A New Method to Infer the Initial Compressive Strength of a Single Concrete Specimen in Its Fatigue Damage Test 混凝土疲劳损伤试验中试件初始极限强度的推测方法
Applying the reliability design theory the initial reliability for critical buckling strength of steel thin-wall cylinder was analyzed in case of maintaining outer pressure test; the scope of initial reliability was discussed under different operating conditions. 应用可靠性设计理论,分析了在保持外压差试验时钢制薄壁圆筒临界失稳强度的初始可靠度,讨论了不同工况下初始可靠度的范围。
From point of view of initial reliability scope of controlling the critical buckling strength, the pressure of thin-wall cylinder under outer pressure test and its limitation were studied. 从控制临界失稳强度的初始可靠度范围的角度,对薄壁圆筒外压试验的压力及其限制进行了研究。
The initial water content, dry density, structural yield stress and soil heterogeneity will affect the shear strength of clay after analysis of test results. 分析试验结果后发现,初始含水率、干密度、结构屈服应力以及土体的非均质性等都会影响粘土的抗剪强度。
The relations of M - r, initial stiffness, the yield strength, failure models, ultimate strength, seismic behaviors and characteristic of dissipation of energy were gained in this test. 通过试验得到了各种连接在循环荷载作用下的弯矩&转角关系、连接初始刚度、连接屈服荷载、破坏形式、破坏荷载、抗震性能和耗能特性。
