With the theoretical analysis of beams strengthened by gluing steel plates , this thesis propose the formulas to calculate the capability of bearing bending under different forms of loading , and the worth of the common function coefficient of steel plates is suggested . at the same time , the concept of premature failure and the standard of failure are brought up . finally , the referencing formulas to calculate the rigidity and deflection of beams strengthen by gluing steel plates are proposed , and the calculating results cohere to the experimental results well 通过对粘钢加固梁的理论分析,文中给出不同形式粘钢加固的抗弯承载力计算公式,并对钢板共同作用系数提出了建议值;同时,文中提出了早期破坏的概念,并给出早期破坏的强度破坏准则;最后,对粘钢加固的刚度和挠度计算提出了参考公式,且与试验结果吻合较好。
Based on elastic methods , the single pile behavior is studied through mindlin stress solution , followed by the analysis of interaction between two piles . thus , the interaction factor is obtained , based on which the interaction between more piles in pile group can be considered using superposition principle 本文以弹性理论法为基础,首先运用mindlin应力解对单桩进行分析,然后分析了两根桩时,桩与桩之间的相互影响,最后根据弹性理论叠加原理,通过引入一个“共同作用系数” ,扩展到群桩中去。
