Basic assumptions of the space truss model.

Basic assumption type	Basic assumption content
Basic assumption 1	The longitudinal bars and stirrups and the concrete diagonal struts are hinged at the nodes to form a space truss structure
Basic assumption 2	It is only considered that the concrete diagonal compression rod bears the axial pressure, and the shear capacity is ignored
Basic assumption 3	Longitudinal bars and stirrups only bear tensile force and do not consider the bolting effect of steel bars
Basic assumption 4	It ignores the torsion resistance of the concrete in the core area
