Secondary beam generation method based on main beam

The invention provides a secondary beam generation method based on a main beam, which solves the problems of poor construction effect of primary and secondary beams of a building and the like, and comprises the following steps of: generating an initial secondary beam scheme according to an original main beam and other elements; preliminarily optimizing the wiring of the initial scheme; adopting a region growing algorithm; shaking the manufacturing area; starting area expansion; eliminating the small areas; and distributing all undistributed areas by adopting a game tree algorithm, and processing and correcting wrong secondary beams again. The method has the advantages of being high in secondary beam design efficiency, convenient to select the optimal solution and the like. 本发明提供了一种基于主梁的次梁生成方法，它解决了建筑主次梁构建效果不佳等问题，其包括如下步骤：根据原始主梁和其他元素生成最初次梁方案；对初始方案接线初步优化；采用区域生长算法；制造区域抖动；开始区域扩张；消灭小区域；采用博弈树算法分配所有未分配区域，再次处理和修正错误次梁。本发明具有次梁设计效率高、方便选取最优解等优点。
