在《工业建筑》1983年第3期上,刊载了王海同志的《铝合金门窗的结构与设计计算》一文。该文虽然详尽地推导了关于挠度计算的公式,但嫌感结合我国实际应用不足,挠度究竟如何计算合适,该文并没有阐述清楚。现特补充一点个人看法如后。大家知道,根据材料力学分析,杆件在均布荷载作用条件下的挠度计算公式是
In the 3rd issue of “Industrial Architecture” in 1983, a paper entitled “Structure and Design Calculation of Aluminum Alloy Doors and Windows” was published by Comrade Wang Hai. Although the formula for the calculation of deflection is derived in detail in this paper, the suspicion of combining the actual application in China is insufficient and how the deflection is properly calculated. This article does not explain clearly. Now add a bit of personal opinion as later. As we all know, according to the mechanical analysis of materials, the formula for calculating the deflection of a member under uniform load is:
