项目摘要

The purpose of this project is to develop a new interactive design method of building frames with visco-elastic (or viscous) dampers. The following results have been obtained in this project.1. An optimal design method has been proposed for shear-flexural building models with visco-elastic dampers. A set of design response spectrum-compatible earthquakes is treated as the design earthquake. The total amount of visco-elastic dampers is specified and the upper bounds of the seismic interstory drifts are constrained in the problem. The sum of the story stiffnesses is the objective function. The gradient projection method has been employed as the optimization algorithm.2. It has been shown that combination of the optimal design method stated in item 1 for reduced models with the static optimal design method for frames is effective in optimally designing building frames with visco-elastic (or viscous) dampers. This method is computationally efficient and enables designers to design passive-damper frames via an interactive designer-computer system.3. A random shaking table experiment has been conducted for the response-controlled three-story model building frame with acrylic visco-elastic dampers. The response-controlled model building frame is designed for the spectrum-compatible design earthquakes. The experiment and the corresponding numerical simulation demonstrate that (1) an equivalent Voigt-type model is a suitable model of the acrylic visco-elastic damper, (2) the accuracy of the numerical model of a frame including such equivalent Voigt-type model is high and (3) the response-controlled design method is a reliable design method for the building frames with acrylic visco-elastic dampers.

该项目的目的是开发一种新的交互式设计方法，以使用粘弹性（或粘性）阻尼器来构建框架。该项目已获得以下结果。1。已经提出了一种最佳的设计方法，该方法针对具有粘弹性阻尼器的剪切芬式建筑模型。一组设计响应频谱兼容地震被视为设计地震。指定了粘弹性阻尼器的总量，并在问题中限制了地震室内漂移的上限。故事刚度的总和是目标函数。梯度投影方法已被用作优化算法。2。已经表明，使用静态的最佳设计方法，用于减少模型的最佳设计方法的组合有效地设计了使用Visco弹性（或粘性）阻尼器的最佳设计构建框架。该方法在计算上是有效的，使设计人员能够通过交互式设计师计算机系统设计被动式受损帧3。已经对具有丙烯酸粘弹性阻尼器的响应控制的三层模型构建框架进行了随机摇桌实验。响应控制的模型构建框架是为彼此兼容的设计地震而设计的。 The experiment and the corresponding numerical simulation demonstrate that (1) an equivalent Voigt-type model is a suitable model of the acrylic visco-elastic damper, (2) the accuracy of the numerical model of a frame including such equivalent Voigt-type model is high and (3) the response-controlled design method is a reliable design method for the building frames with acrylic visco-elastic dampers.
