单跨梁都是由粱和地基按两刚片规则组成的静定结构，因而其支座反力都只有三个，可取全梁为隔离体，由平面一般力系的三个平衡方程求出。

Single span beam is a statically determinate structure composed of beam and foundation according to 2-body rule, there are 3 reaction forces which can be determined by isolating free body and solving the equilibrium equation of forces.
