Mesoscopic steel reinforced concrete column section modeling method with controllable parameters
The invention relates to a mesoscopic steel reinforced concrete column section modeling method with controllable parameters, which is a method for generating two-dimensional convex polygon concrete coarse aggregates and judging whether the coarse aggregates are mutually overlapped and whether the coarse aggregates and the section steel are mutually overlapped. The method is an auxiliary (preposed) method for finite element modeling of the micro-scale steel reinforced concrete. The method has the following characteristics: (1) the convex polygon is used for simulating the concrete coarse aggregate, and the aggregate parameters are adjustable; (2) a mesoscopic concrete model containing profile steel in various shapes can be established according to requirements; (3) based on an MATLAB command, the model generation speed is high; and (4) a putting point marking method is used during putting, so that the judgment steps and the determination of a putting position are simplified, and the model generation speed is further accelerated.
本发明涉及一种可控参数的细观型钢混凝土柱截面建模方法，是一种二维凸多边形混凝土粗骨料生成、判断粗骨料之间、粗骨料与型钢之间是否互相重叠的方法，投放粗骨料时模型内部能够预留型钢构造孔洞，是细观型钢混凝土有限元建模的辅助(前置)方法。该方法有如下特点：(1)使用凸多边形模拟混凝土粗骨料且骨料参数可调；(2)可根据需求建立包含各种形状型钢的细观混凝土模型；(3)基于MATLAB命令，模型生成速度快；(4)在投放时使用投放点标记方法，简化了判断步骤和投放位置的确定，进一步加快模型生成速度。
