摘　　要：析了“规范”中没有规定的附加风压力和附加风吸力以及多连拱形屋面的风载体形系数，并以一个主架和四个次架相间排列的三连拱温室为例，建立了它的计算模型，研究了它的力学特性。in this study,the author analyses the additional wind pressure and the additional wind suction as well as the shape factor of wind load for multi-arch roof coverings,which are not yet mentioned in the current constructional standards. As an example,the author sets up a calculating model for a tri-arch greenhouse arranging alternately a main framewith four sub-frames,and studies its mechanical properties.
