[摘要] 為了追求美觀，別墅大多采用坡屋面形式。實(shí)際上，坡屋面呈現(xiàn)空問(wèn)受力的特性；然而，在受力計(jì)算時(shí)，設(shè)計(jì)人員為了追求方便、快捷，一般采用平面模型的計(jì)算結(jié)果來(lái)代替空間計(jì)算結(jié)果，雖然結(jié)果通常保守、安全，但卻掩蓋了一些坡屋面所固有的受力特點(diǎn)。通過(guò)一個(gè)工程加固實(shí)例，利用有限元軟件進(jìn)行了幾種荷載組合情況下的空間計(jì)算分析，并提出了具體的加固方案，總結(jié)了該類結(jié)構(gòu)在設(shè)計(jì)中應(yīng)注意的問(wèn)題。

Abstract: In order to pursue appearance beauty, sloping-roof are mostly adopted in villas. Actually, the sloping-roof shows the characteristic of spatial. But, in fact, the designers mostly prefer plane models to spatial models for sake of convemence. Although the results of the former would be generally much bigger and safer than that oflatter, it conceals many facts which belong to the sloping-roof of a villa. Based on an actual example which needs to be strengthened, this article mainly introduced the correlative problems to pay attention to designing processes by analyzing this kind of structure in different loads and designing the strengthening methods.
