说明：  两端固支的平板结构，载荷沿厚度均匀分布，且载荷集度为q=100 . 板长为10m，高h=2m，厚度为t=20cm，弹性模量E=210GP，泊松比为μ=0.3，不计自重。采用四节点等参单元进行有限元分析。
(The plate structure at both ends is distributed uniformly along the thickness, and the load set is q=100. The length of the plate is 10m, high H =2m, the thickness is t=20cm, the modulus of elasticity is E=210GP, and the Poisson's ratio is =0.3, without weight. Four node isoparametric element is used for finite element analysis.)
