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

密苏里-罗拉大学与大连理工大学在中国联合开展了多约束、多目标函数的三维柔性刚体结构优化设计研究。这些约束包括稳定性、侧向扭转运动、设计规范规定的允许位移、应力和各种加载条件下的P效应。研究工作集中在1)钢筋混凝土和钢结构建筑系统的结构建模，2)开发不同建筑材料建造的大型结构的优化算法，3)建立包括建筑和损坏成本的目标函数，4)各种结构的最佳设计参数的适用性和可靠性研究，5)选定结构系统的损伤模型的实验验证，以及6)制定基于最优的设计准则和评估现行设计规范的规定。合作研究应该提供一个独特的机会，以获得和统计验证新的结果，以改进目前的设计实践。

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.
