thermal compressive stress

A worked example given at the end of this paper shows that the difference between the tensile and compressive creeps of the fly-ash concrete will cause great influence on the thermal creep stress of structures.

文末算例说明，在一般混凝土坝中掺加粉煤灰后，由于混凝土的拉压徐变不相等，对其温度徐变应力有相当的影响。

Load tensile stress and the thermal compressive stress vertical of interface concentrated at the end of the bond interface, but the tensile was greatly higher.

而垂直于界面分布的由加载力形成的拉应力远大于残余应力形成的压应力，并且趋向于界面边界点应力逐渐增大。

Although the actions of the residual compressive strains and the residual contractive thermal strains are equivalent for causing the welding residual stress, it is useful distinguishing them to develop new measures relieving and adjusting the welding residual stress in practical joints.

虽然残余压缩应变和残余收缩应变在导致焊接残余应力产生的作用方面是等价的，但其机理却有本质的不同，区别二者有利于研究和开发新的焊接残余应力调控技术。

Therefore, rigid jointless track laying must be carried out under specific thermal conditions to avoid dangerous tensile and compressive stress in the rails during extreme weather.

因此在铺设无缝线路时，钢轨温度需要保持在一定的范围内，以避免恶劣气候条件下钢轨内部产生的拉伸应力对其产生的损害。

Under rarely and commonly seismic loads, different filling materials and filling ways, will have a greater impact on tensile compressive stress and shear stress of lightweight thermal insulation wall slab, thereby affect seismic performance of structures.

在多遇和罕遇地震作用下，不同的填缝材料和填缝方式，会对轻质保温板的剪切应力和拉压应力产生较大影响，进而影响结构的抗震性能。
