The loading - displacement curve was consistent with the loading - energy curve , and the both could explain the whole dynamic course and the phenomena of dynamic instability 结构的荷载一位移曲线与荷载一应变能曲线具有一致性,都能体现结构的动力变化过程和解释动力失稳的现象。
A corresponding program is developed . nonlinear load - displacement curve in complete - process analysis of a double - layer reticulated shell structure is traced out by the program 研制了相应有限元程序,对网壳结构进行非线性的荷载?位移全过程跟踪分析,得到网壳结构荷载?位移全过程曲线。
The load - displacement curves and moment - curvature curves that calculated from the full - course analysis program are in accordance with the resuits of experimental especially in prime period of ioad presents the program is avaiiable 试验和全过程分析得到的荷载-挠度曲线对比表明:在加载前期两者的曲线吻合较好,证明全过程分析能反映碳纤维加固梁的受力特点及程序的正确性。
With the modeling method in this paper , it is showed that numerical load - displacement curves agree well with the experimental skeleton curves , and that the errors of crack load are bigger , but the cra 分析表明:采用本文的建模方法,计算所得的荷载?位移曲线与试验所得的骨架曲线符合较好;开裂荷载有的误差较大,但开裂部位及过程与低周反复荷试验中某一方向加载所得的结果较为符合。
In the elastic term , the two load - displacement curves slope are similar , the new structure s slope is more greatly . stiffness is better than the traditional structure . but the new joint s crack load is littleer 在弹性阶段两者的荷载-位移曲线斜率相差不多,而且新的连接形式斜率还大一些,它的刚度较传统连接形式要好,但新的连接形式楼板开裂荷载稍偏低,应采取加强措施来提高开裂荷载。
