桁架(A truss)：由直杆组成的铰接体系 assemblage of straight members connected at their ends by hinged joints

桁架基本假设（Basic assumptions）:

1、各结点为理想铰；all hinges are frictionless

2、各杆轴线为直线,所有用铰联结的杆交于铰心；The centroidal axes are straight lines,those meeting at a hinge all intersect  at the centre of hinge.

3、荷载只作用于结点上。All loads are applied on truss only at its joints.
