| 5. | The elastic mechanics solution of hyperstatic beams with single span under the action of even load 局部荷载作用下有梁矩形板的弹性分析 |
| 6. | The experiment procedure and analysis result about exteriorly extended end - plate connection with high strength bolt are introduced primarily ; each sample ' s dimension is given . the adding load equipment , measuring apparatus placed , measuring point established is detailed . adding load measure load and m - curve is produced ; the single span gabled frames horizontal displacement formula is deduced when the horizontal concentrated force is applied to it 重点介绍了外伸端板高强螺栓连接的实验过程及实验分析结果,介绍了各组试件的形状尺寸、加载装置、测量仪器安放、测点的布置等;给出加载方式及测出的m -曲线;计算出试验节点的初始刚度;推导水平集中力作用下单跨门式刚架考虑节点半刚性的侧移计算公式。 |
| 7. | A material nonlinear finite element analysis for the cast - in - place reinforced concrete hollow slab that occurs from initial loading , cracking , yielding to failing is carried on . the cracking load , ultimate load , the displacement rules and the principal stress distribution rules of the hollow slab under the vertical loads are obtained . a material nonlinear finite element analysis for the single span hollow flat - plate floor is also carried on 其次对空心板进行了从加荷、开裂、屈服直至破坏的全过程材料非线性有限元计算,得到了空心板在竖向荷载作用下的开裂荷载、极限荷载及位移和应力分布规律;还对单跨无梁楼盖进行了材料非线性有限元计算,通过分析主应力场明确了柱上暗扁梁的作用;有限元计算的结果验证了以上的理论分析并得到了一些重要的结论,对改进现浇空心板无梁楼盖的构造措施有重要的参考价值。 |
| 8. | The dynamic characteristics of lightweight steel structure are also respectively calculated and analyzed in single span or whole structure . the computational results show that the out - planar stiffness has great influences on dynamic characteristics during the single span calculation ; in the total structural analysis the crane has no evidently effect on dynamic characteristics with contrast to single span 对轻钢厂房结构的单跨和整体结构进行了动力特性计算分析,结果表明平面外刚度对动力特性的影响非常显著,在空间结构模型分析中吊车质量对结构的影响并未比平面单跨情况下来得明显。 |
