 4. 支吊点荷载计算方法 (Calculating Method of load at the bearing point)
4.1 进行支吊架配置设计时应取得下列资料：
The following information is necessary for the design:
(1) 管线名称代号，管道材质、外径和壁厚，输送的介质及其温度，绝热层材质及厚度，支吊处管线走向，管中心 (管底) 标高。
The name and the code name of the pipeline,pipe material,O.D.and the thickness of pipe,transmitting medium and its temperature,insulator materital and its thickness,the orientation of the pipeline,hight of pipe center.
(2) 支吊生根处的条件，混凝土强度及空间结构尺寸，钢结构的形状，尺寸及空间位置。
The insert condition,the strength of concrete and the space condition ,the steel structure,its size and space Iocation.
4.2 进行支吊点荷载计算时，主要计算管线自重 (包括管道、流体、绝热层、法兰、阀门等) 和流体反力。
室外管道还应计算风、雪荷载。
When calculating the bearing point load,the main factors are the weight of pipeline (including pipe,fluid,insulator, flange and valve) and the reacting force of fluid.Wind and snow load should also be taken into consideration for outdoor pipes.
