【摘要】 在结构计算软件日益普及的今天,设计人员只需作必要的数据输入,计算机就会给出计算分析结果。然而对绝大多数设计人员而言,计算软件是一个“暗箱”,人们无法监控其计算和处理的全过程,这就要求设计人员必须具备清晰的结构概念,并对所使用的结构计算软件的基本假定、计算模型和适用范围有所了解,并从整体上控制结构性能,这样才能保证结构的安全、经济、合理。更多还原

【Abstract】 By the popularization of structure calculating software, designers of nowadays only need to input necessary data to the computer and then get the final result of calculation and analysis. But calculating software itself is a `camera obscure’ to most of the designers due to the fact that the total process of calculating and processing might be beyond monitoring and control. Structure designers must possess of realizing structure concept so as to comprehend the elementary hypothesis, calculating model and extent of application of the calculating software, therefore to make better control of strucure performance to ensure its safety, economical cost and rational quality.更多还原
