| 摘 要： | 抛物线形空间刚架的力学计算十分复杂 ,在已有的手册、资料、教材中均未叙及。本文根据虚功原理 ,建立了抛物线的弯矩、扭矩、剪力表达式。算出了其在任意荷载作用下的位移 ,推出了弯矩、扭矩、剪力及分布荷载间的微分关系。

| Abstract: | The mechanics calculation of parabolic space rigid frame is v ery complicated,without being dealt with in issued directories,documents and tex tbooks.Based on virtual work theory,expressions for bending moment,torque and sh ear of parabola were established,by which their displacement by arbitrary load w as worked out,and the differential relationship among bending moment,torque,shea r and distribution load was inferred in this paper. |
