Effect of Web Openings on Flexural Behaviour of Underground Metro Station RC Beams under Static and Cyclic Loading

Table 6

Key characteristics of the load-deflection responses of the RC beams with various openings under static and cyclic loading conditions.

Specimen		Cracking load (kN)		Yield load (kN)		Ultimate load (kN)
		Reverse	Forward	Reverse	Forward	Reverse	Forward
Static	Beam O	56		328.9		396.1
	Beam T	41		198.2		233.8
Cyclic	Beam R	200	200	375	435	600.4	492.3
	Beam O	150	150	530	620	740.6	652.4
	Beam T	120	120	400	400	487.2	433.6
