1 前言 随着计算机硬件功能的日益强大和软件技术的不断发展,以计算机系统为平台的多媒体教学应运而生。由于具有形象,生动,直观等特点,多媒体教学软件一出现就受到了各方面的重视和越来越广泛的应用。但现在流行的多媒体教学软件大多都是关于计算机软硬件知识的,其他专业的教学软件很少见到,土木工程专业的教学软件在软件市场上几乎没有。而本专业的课程《钢筋混凝土构件》中的钢筋混凝土简支梁受力性能一直是专业教学的重点和难点,不少学生(包括笔者)都感觉学完这部分内容后并未学深学透,知其然而不知其所以然,虽然会套用公式做题,对混凝土梁在荷载作用下的状态认识并不是非常清楚。为了填补本专业教学软件的空白,更好的促进本专业的教学,笔者开发了这个钢筋混凝土简支梁加载试验模拟CAI系统。 2 软件的理论背景
1 Introduction With the growing power of computer hardware and software technology continues to develop, the computer system as a platform for multimedia teaching came into being. Due to its vivid, vivid and intuitive features, multimedia teaching software has been valued by all aspects and applied more and more widely. However, most popular multimedia teaching software nowadays are all about the knowledge of computer hardware and software, and other professional teaching softwares are seldom seen. There are almost no teaching softwares for civil engineering in the software market. However, the mechanical properties of reinforced concrete beams in the “reinforced concrete component” of the professional course have always been the focus and difficulty of the specialized teaching. Many students (including the author) feel that they have not studied thoroughly after learning this part However, I do not know why, although the formula will be applied to do the question, the state of the concrete beam under load action is not very clear. In order to fill the gap of the professional teaching software, to better promote the teaching of this specialty, I developed this reinforced concrete simply supported beam loading test simulation CAI system. 2 software theory background
