坡屋面计算模型（Slope roof calculation model） Slope roof structure calculation of slope roof structure design The design of slope roof structure Because of the program itself, mainly in view of the PM module under construction model limitations, the slope roof structure design, can not be carried out in accordance with the actual situation modeling (unless the space modeling module SpasCAD), namely the upper inclined beam not directly on the pillars, when you use the PM model under the oblique beam must have at least 200 mm high short column to support, and inclined roofing is separately built a standard layer, at the end of the oblique beam on the standard layer at least 200 mm high of short column, so as not to cause the load transfer error. Another problem, since the slant roof board is currently unable to calculate and process, it has to be simplified. Currently, there are three calculation models for sloping roof structure: 1. Modeling with SpasCAD, modeling according to the actual situation, without any simplification. Calculate with PMSAP 2. The stiffness contribution of the inclined roof is neglected, and the load and the weight of the roof are added to the beam on the four sides according to the situation of the two-way plate, and the PM modeling is used for the analysis and calculation with SATWE or TAT 3. The stiffness of the roof board is simulated by inclined support, which is to replace the roof panel with inclined support on the roof, and also consider the load on the roof of the roof. Model with PM, and analyze with SATWE or TAT. To sum up the above three models, the first model many design institutes do not have the software requirements. Compared to the second and the third, the third model is more close to the actual situation, whether in the cycle, displacement, stiffness etc. In the first the calculation of the model is more close to, so suggest you use the third kind of calculation model.
