Development of Web-Based Real Time Virtual Model Based Simulation Laboratory for Soil-Structure Interaction Problems

该项目利用有限元技术开发了一个基于Web的虚拟模型模拟实验室(VMBSL)模块，该模块具有图形和动画功能，用于研究钢结构框架在静力荷载(重力、风等)作用下的性能，包括它们各自的混凝土基础和地基土模型，以便在结构工程课程中实施。其目的是通过将框架结构的真实行为与支撑它们的土壤和基础属性相结合，将土木工程课程中的结构和岩土工程课程结合起来。它还涉及结构体系的问题，从地面到描绘整个结构的真实行为。基于Web的VMBSL和动画模块被纳入两门本科课程，即结构分析和钢结构设计。本项目中开发的VMBSL工具提供了示例，以演示与理想化的二维模型相比，实际的梁-柱和柱-基础连接的三维模型、混凝土基础和土属性如何影响结构体系中的横向摆动和杆件受力。这些模块促进互动学习、虚拟环境、基于团队的项目和终身学习体验的环境。

The project develops a Web-based virtual model-based simulation laboratory (VMBSL) module with graphical and animation capabilities using the techniques of finite element method (FEM) to study the behavior of steel building frames subjected to static loads (gravity, wind, etc.), including their respective concrete foundation and foundation soil models, for implementation in structural engineering courses. The objective is to couple structural and geotechnical courses in civil engineering curriculums by integratingthe true behavior of frame structures with soil and foundation properties that support them. It also addresses the issue of structural systems from grounds up to delineate the true behavior of the entire structure.The Web-based VMBSL and animation modules are incorporated into two undergraduate courses, namely structural analysis and steel design. The VMBSL tools developed in this project provide examples to demonstrate how the three-dimensional model of actual beam-to-column and column-to-foundation connections, concrete foundation, and soil properties effect the lateral sway and member forces in the structural systems as compared with the idealized two-dimensional models. The modules promote an environment for interactive-learning, virtual environment, team-based projects, and lifelong learning experiences.
