摘　　要：本文就建筑幕墙竖料计算中遇到的各种力学模型进行分析和概括,提出了任意单根梁的通用力学计算模型,并就通用力学计算模型推导了该梁任意梁截面处的弯矩方程和挠曲位移方程及它们在极点处的极值和支座反力计算公式。由通用力学计算模型公式进而推导出多跨静定梁、多跨一次超静定梁、单跨静定梁、单段双跨梁、多段连续双跨梁、简支梁的相关方程和计算公式。This paper analyzes and generalizes all kinds of mechanical models encountered in the calculation of mullions for building curtain wall,and puts forward a general mechanical calculation model for arbitrary single beam.The bending moment equation and flexural displacement equation at any section of the beam are derived for the general mechanics calculation model,and their extreme value at the pole and the formula for calculating the reaction force of the bearing are derived.Based on the general formula of mechanical calculation,the equations and calculation formulas of multi-span statically determinate beam,multispan primary statically indeterminate beam,single-span statically determinate beam,single double-span beam,multi-continuous double-span beam and simply supported beam are derived.
