Multi-Objective Optimization of 3-D Flexible and Stiff Structures with Compromise and Game Algorithms

提出了美国密苏里大学罗拉分校与中国大连理工大学的联合研究项目，研究具有多约束和目标函数的三维柔性和刚性结构的优化设计。约束条件包括稳定性、横向扭转运动、设计规范规定的允许位移、应力和各种载荷条件下的P-效应。研究工作集中在1)钢筋混凝土和钢结构体系的结构建模，2)开发不同建筑材料建造的大型结构的优化算法，3)制定包括施工和损坏成本在内的目标函数，4)各种结构的最佳设计参数的适用性和可靠性研究。5)对选定结构体系的损伤模型进行实验验证；6)制定基于优化的设计准则，并对现行设计规范条款进行评估。合作研究应该提供一个独特的机会来获得和验证统计上的新结果，以改善当前的设计实践。

A joint research project between the University of Missouri-Rolla and the Dalian University of Technology in China is proposed to study optimum design of three-dimensional flexible and stiff structures with multiple constraints and objective functions. The constraints include stability, lateral-torsional motion, design code provisions of allowable displacements, stresses, and P- effects for various loading conditions. Research efforts are concentrated on 1) structural modeling of reinforced concrete and steel building systems, 2) development of optimization algorithms for large structures built of different construction materials, 3) formulation of objective functions including construction and damage costs, 4) serviceability and reliability studies of optimum design parameters of various structures, 5) experimental verification of the damage model for a selected structural system, and 6)development of optimum-based design criteria and assessment of current design code provisions. The collaborative study should provide a unique opportunity to obtain and validate statistically the new results for improving current design practice.
