初始荷载 meaning in English

initial load

Meanwhile , the results of program show that , under secondary load , the bonding - reinforced beams " yield - moment would decrease as the original load increase , but the original load would n ' t remarkably influence the ultimate flexural capacity
同时，程序计算结果表明，加固梁在二次受力的作用下，屈服弯矩随着初始荷载的增加而减小，但极限抗弯承载力受初始荷载影响较小。
The beams under secondary loading ( namely the preloading was not removed ) are firstly studied in this dissertation , and the ultimate strength , stiffness , and the distribution of cracks of the beams strengthened with ferrocement have been analyzed . mid - span deflection , crack width and strains of steel were measured during the course of the test , and performances of the beams are compared and assessed with particular emphasis on cracking behavior , mid - span deflection , ultimate strength capacity , the modes of failure and so on
本文首次对二次受力(初始荷载不卸除)试件进行了加固试验研究,试验中测量了试件的极限荷载、混凝土应变、钢筋应变及钢筋网应变等,对比了加固与未加固构件的裂缝开展、跨中挠度以及极限荷载情况,并研究了用该方法加固的梁在各种受力情况下可能产生的破坏形式等。
