Uncertainty-Based Optimal Structural Design

9522654 Panteldes凸建模的概念为分析有限信息量的系统中的不确定性提供了一种有吸引力的替代方案。将开发的优化算法将用于最小化结构系统在不确定静载、自应变不确定因素(如制造误差、温度梯度、支座沉降)以及上述不确定因素的组合下的体积。将对连接位移和杆件应力施加约束。不确定性的另一类问题是使结构旋转或跨国支承弹簧的体积最小化。对杆件应力和连接位移施加约束。另一类不同类型的问题是当减振器和主结构的阻尼和频率特性存在不确定性时，最小化配备动力减振器的主结构的幅度。对结构性能不确定的结构在不确定地震激励下的优化设计也进行了研究。最后对不确定地震作用下土-结构相互作用特性不确定的结构进行最小体积设计。

9522654 Pantelides The concept of convex modeling provides an attractive alternative for analysis of uncertainty in systems for which a limited amount of information is available. The optimization algorithms to be developed will be used for minimizing the volume of a structural system under uncertain static loads, self-strained uncertainties such as fabrication errors, temperature gradients, support settlements, and a combination of the above uncertainties. Constraints on the joint displacements and member stresses will be imposed. Another type of problem with uncertainty is that of minimizing the volume of a structural rotational or transnational supporting springs. Constraints on member stresses and joint displacements are imposed. A different type of problem is one of minimizing the amplitude of the primary structure equipped with a dynamic absorber when uncertainties exist in the damping and frequency characteristics of the vibration absorber and the primary structure. The optimum design of structures with uncertain structural properties, under uncertain earthquake excitations will also be performed. Finally the minimum volume design of structures with uncertain soil- structure interaction properties, under uncertain earthquakes will be performed.
