In chapter 3, on basis of the first order shear deformation theory, a series of composite laminated beam elements are developed, which are plied transversely, longitudinally and/or assembled both, respectively. A geometric nonlinear element stiffness matrix for the transversely plied laminated beam is presented.

第三章首先介绍了目前已有的在小变形下的横向层合梁、纵向层合梁和组合层合梁理论，并推导了其相应的有限元列式，然后又基于Von-Karman大挠度理论的几何关系，推导了大变形下横向层合梁的单元切线刚度阵。

The results of lattice beam internal force calculated method based on double parameter groundsill model are more approach the experiment measured values because of consideration of the pass of shearing force in soil, and its calculated workloads are similar with the method of winkler elastic foundation. Besides, the thesis also discusses the moment of torque affected results on node stress situation and the correction of stress value at the bottom of cross node of lattice beam. Due to the repeat calculation of node area during internal force calculation, the stress value of the bottom of beam is lower, this may lead the calculated value unsafe, but the corrected stress value will more approach to practical situation.

对格构梁的内力计算提出基于双参数地基模型的格构梁内力计算方法，其计算结果表明，双参数地基模型上的格构梁内力由于考虑土中剪力的传递更加接近于试验实测值，其计算工作量与winkler弹性地基梁法相当，此外，文中还探讨了扭矩作用对格构梁节点受力情况的影响结果以及格构梁交叉节点底部的应力值的修正，由于内力计算过程中节点处的面积被重复计算，使得梁底应力偏小，可能导致计算结果的偏于不安全，修正后的应力值更接近于实际情况。

The results show that, for the first with no headwall, when there is no crosswind, it has small front face areas, so the aerodynamic resistance is the least. Since the second and the third have headwall, the front face areas are large, so they have bigger aerodynamic resistance. Under the condition of crosswind, as the third design option has the highest side beam, the area of positive pressure at the upwind is bigger, and the area of negative pressure is smaller when the bigger eddy area appears, so the side forces become larger. The first has the least side forces; the overturning moment of the first is the least.

The properties of blast loading are that it is highly impulsive, exhibiting high-pressures but lasting for a very short duration. The propagation process of shock wave produced in steel-concrete composite beams subjected to blast loading is very short. And there is only small deformation for the beam during the time of the propagation process of wave.

由于爆炸荷载作用时间短、超压峰值大等特点，当爆炸荷载作用于钢－混凝土组合梁上时，将在梁内产生冲击波，冲击波在钢－混凝土组合梁内的传播过程极短，并且在冲击波的传播过程中梁的变形很小，因此，可将冲击波在梁内的传播过程进行独立分析。
