| 中文摘要: |
| 本文采用(0,1)规划法对具有矩形或T形截面的钢筋混凝上梁进行优化设计。为了符合工程设计要求,截面尺寸采用整型的离散变量,取梁的总造价为目标函数,约束条件包括强度、裂缝扩展宽度、挠度、配筋率、尺寸及其它规范要求。在求得梁的最优尺寸及相应的配筋量之后,再根据设计知识和优化理论建立起钢筋混凝土梁自动优化选筋的优化模型,然后按照(0,1)规划法进行优化选筋。文末的几个例题充分说明了本文方法的有效性和可靠性。 |
| 英文摘要: |
| In this paper,the (0,1) programming method is used to the optimun design of reinforced concrete beam with rectangular and T-shaped sections . According to the demands of engineering design, sizes of section are adopted as discrete variables , the object function is the total cost of beam, the constraints are these, such as the strength material, propagation width of crack, deflect ion, percentage of reinforcement, sizes and all other requirements in code.After finding optimum section of beam and corresponding amount of reinforcement, the mode! of automatically optimum selection reinforcement T. C. beam is established according to the design code and optimization theory and the (0,1) programming method is then used to select the reinforcement. Some examples show the efficiency and reliability of this method. |
