Use of Immersive Virtual Environments As A Collaborative Tool For The Study of Architectural Building Components Subjected to Earthquake Excitations

本研究的主要目的是：研究不同的方法来实现和连接可视化应用程序到现有的计算机软件分析结构。研究地震期间建筑构件的行为及其与建筑物结构构件的相互作用。该项目侧重于虚拟环境计算机软件开发的研究，该软件可以帮助更好地理解建筑组件设计领域，特别是分区和吊顶系统。本项目分为两个阶段。在第一阶段，将创建计算机软件（VIRTUAL-SAP）来开发“智能建筑模型”。这是一个建筑的虚拟现实模型，通过中间软件连接到一个结构分析程序。PC-SAP4（结构分析程序）最初是由加州大学伯克利分校土木工程系开发的，在过去的25年里已经被测试并应用于各种问题。本项目将使用PC-SAP4对建筑结构进行结构分析。CAVE （CAVE Automated Virtual environment）将用于生成建筑结构模型。该系统将允许用户将自己“沉浸”在一个虚拟世界中，该世界拥有构建完整结构模型所需的所有工具，包括加载，适合分析和设计。作为已开发计算机程序应用的一个例子，该项目的第二阶段涉及使用第一阶段开发的软件（VIRTUAL-SAP）来研究模拟地震荷载下不同建筑构件的行为，并为建筑师和承包商提供对这些构件行为的理解。这些元素与结构的相互作用以及在低地震和中地震运动下的相互作用将被证明和研究。将考虑连接单元和边界条件的不同配置。

The main objectives of this research are to:Investigate different methods of implementing and linking a visualization application to existing computer software for the analysis of structures. Study the behavior of the architectural components and their interaction with the structural elements of buildings during earthquakes.This project focuses on the studies resulting in the development of a virtual environment computer software that can help provide better understanding in the area of the design of architectural components specially partitions and suspended ceiling systems. This project consists of two phases. During the first phase computer software (VIRTUAL-SAP) will be created to develop "Smart Building Models". This is a virtual reality model of a building which is linked through intermediary software to a structural analysis program. PC-SAP4 (Structural Analysis Program) originally developed at the Department of Civil Engineering of the University of California, Berkeley, has been tested and applied to various problems during the past 25 years. This project will use PC-SAP4 for the structural analysis of building structures. The CAVE (Cave Automated Virtual Environmental) will be used for the generation of the building structural model. The system will allow the user to "immerse" him/herself in a virtual world that has all the tools required to build a complete structural model, including loading, suitable for analysis and design. As an example of the application of the developed computer program the second phase of the project involves the use of the software developed in the first phase (VIRTUAL-SAP) to study the behavior of different architectural components under simulated seismic loading and provide an understanding of the behavior of these elements for the architects and contractors. The interaction of these elements with the structure and with each other subjected to low and moderate earthquake motions will be demonstrated and studied. Different configurations of connecting elements and boundary conditions will be considered.
