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.

该项目开发了一个基于Web的虚拟模型仿真实验室（VMBSL）模块，该模块具有图形和动画功能，使用有限元法（FEM）技术研究钢建筑框架承受静态载荷（重力、风等）的行为，包括其各自的混凝土地基和地基土壤模型，以用于结构工程课程。其目的是通过整合框架结构的真实行为与支持它们的土壤和基础特性，将土木工程课程中的结构和岩土工程课程结合起来。它还解决了结构系统的问题，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个本科课程，即结构分析和钢结构设计。在这个项目中开发的VMBSL工具提供的例子来演示如何实际的梁-柱和柱-基础连接的三维模型，混凝土基础，和土壤特性的影响，在结构系统中的横向摇摆和成员的力量相比，理想化的二维模型。这些模块促进了互动学习、虚拟环境、团队项目和终身学习体验的环境。
