“混凝土结构基本原理”虚拟仿真实验教学探讨

Discussion on Virtual Simulation Teaching of Fundamental of Concrete Structures

为满足新工科背景下的实践型和创新型人才培养需求,针对“混凝土结构基本原理”课程的重点和难点,以教学目的为核心,使用Python编程语言的PySide开源框架,研发了虚拟仿真教学平台。平台包括材料力学性能模块和基本构件模块,其开发架构分为控制调用、参数设置、通用有限元软件计算、数据存储模块和显示等五大模块。利用平台,学生能开展开放型、自主设计型的实验,直观观察结构在加载过程中内部的应力、应变变化,以及裂缝开展、结构破坏过程,深入理解结构破坏机理,掌握材料力学性能及构件设计理论。提出了基于该教学平台的虚实结合的教学方法及其在创新人才培养中的作用。

To satisfy the goal of training practical and creative talents based on new engineering education,aimed at core knowledge of the course “Fundamental of Concrete Structures”,a virtual simulation teaching platform was developed using Python with PySide framework,a third-part open-source python library.The platform includes the material mechanical properties module and the basic elements module,and its development framework consists of five sections:control module,parameter-assignment module,finite-element-method calculating module,storage module and display module.Students can design and carry out virtual experiments by themselves using this platform.Besides,they can observe real-time stress and strain of the structure during loading process,as well as the development of cracks and the process of structural failure,which is significant for students to deeply understand the mechanism of structural failure,the mechanical properties of materials,and the theory of basic elements design.The teaching method based on virtual simulation teaching platform is proposed and its function on training innovative personnel is analyzed.
