1 引言 在建筑结构设计领域,由于存在结构设计计算量大、绘图复杂的特点,CAD的开发和应用走在了本领域的前列。目前,结构CAD软件的开发,呈现出两方面的发展趋势:一是不断发展结构计算理论。利用计算机高速运算的特点,解决现阶段日益增加的高层、超高层、大跨度及悬挑结构的力学及强度计算问题。二是悉心研究现阶段的结构工程师计算机辅助设计绘图的特点,解决设计人员绘图工作量、出错率高、效率低下的问题,将设计人员从大量的繁琐的绘图中解脱出来,用计算机处理各种文件图纸,把精力用于创造
1 Introduction In the field of building structure design, the development and application of CAD is at the forefront of the field due to the large amount of structural design and complexity of drawing. At present, the development of structural CAD software presents two trends: First, the continuous development of structural computing theory. Utilizing the characteristics of high-speed computing of computers, the problem of mechanical and strength calculation of high-rise, super-high-rise, long-span and cantilevered structures is being solved at this stage. Second, careful study of the structural engineer at this stage the characteristics of computer-aided design drawings to solve the problem of designers drawing workload, high error rate, low efficiency, designers will be freed from a large number of cumbersome drawings, the use of computer processing Document drawings, to use energy to create
