[關(guān)鍵詞] 圬工拱 梯形梁元 有效深度 迭代法 彈性模量 抗壓強(qiáng)度A tapered beam element model is used to simulate the behaviour of an arch structure under loading. At each load increment, an iterative method is adopted to predict displacement. The model is simple and the analysis shows good convergence characteristics. Some numerical results are compared with arch load test, which show that a reasonable accuracy can be achieved.
Keywords: tapered beam element; effective arch depth;iterative method; elastic modulus
