荷载比 meaning in English

loading ratio

Comparison including the cracking , yielding and ultimate loads of the beam , load - displacement curve , envelop curve , the ductility and energy - dissipation capacity were made between the response of the specimens before and after strengthening . test results indicated that the yielding loads of the specimens after strengthening were improved from 12 . 3 percent to 17 . 2 percent and the improvement of specimens rehabilitated by jacketing was higher than that of the bonding steel plates one
加固后试件破坏同样发生在梁端，屈服荷载比加固前提高12 . 3 17 . 2 ，与粘钢加固相比，加大截面法加固的试件承载力提高幅度较大；加固后试件的延性和耗能性能比加固前有很大的改善，其中以粘钢加固的试件提高最为明显。
