Precast Seismic Structural Systems (PRESS)-Task 1.4 Analytical Platform Development

这是协调研究计划的一部分， 预应力结构体系 为了研究 两种连接类型的广泛行为，一种灵活的 将建立分析平台。 该平台将 计算机分析程序DRAIN 2D-X的扩展， 适应三维元素的发展， 包括奴役限制，并加强目前可用 前处理和后处理工具， 非线性静态和动态分析程序 结构. 还将开发特殊用途的要素。 这些将基于物理光纤模型， 不同层次的分析复杂度。 重要组成部分 的全部努力将用于记录 分析平台基础的分析程序 为了便于列入特殊目的 其他项目参与者。 文件将 还提供指导其他参与者和用户在 程序的使用。 本项目将发展基本分析能力 需要进行的所有研究涉及的整体 地震预制结构研究计划。

This is a part of the coordinated research program in prestressed structural systems. In order to study the behavior of the two broad types of connection type, a flexible analytical platform will be developed. This platform will be an extension of the computer analysis program DRAIN 2D-X to accommodate the development of three-dimensional elements, to include slaving constraints and to enhance presently available pre-and post-processing tools while refining current procedures for the nonlinear static and dynamic analysis of structures. Special purpose elements will also be developed. These will be based on physical fiber models and will permit various levels of analysis sophistication. Significant part of the total effort will be directed towards documenting the analytical procedures which underlie the analytical platform in order to facilitate the inclusion of special purpose elements by other program participants. Documentation will also be provided to guide other participants and users in the use of the program. This project will develop the basic analytical capability necessary to carry out all the studies involved in the overall seismic precast structure research program.
