| 摘 要： | 在考虑雪载的情况下,依据结构力学的基本原理,提出了一种不经过有限元的复杂计算、概念明了、方法简易的确定温室拱轴线的新方法。利用该方法对温室的拱轴线进行研究,发现雪载对拱半径的影响很小,拱半径随温室单跨增大而增大,拱半径与矢跨比的关系比较复杂,并为快速确定拱半径参考值提供一张表。

| Abstract: | A simple optimized algorithm based on the principle of arch of structure mechanics to define the arch line of arch greenhouses is developed.Using the method,the radius of greenhouses arch,which is in proportional to the span of the greenhouses and its independent of snow load,is studied.The relationship of the ratio of the arch height to span and the radius of greenhouses is complex.A table of reference value of greenhouses radius is presented for the greenhouses design to evaluate the radius.The method is economical,effective,simple and practical. |
