Crack inducers were used to prevent cracking from spreading. 2) Loads were applied in increments until a permanent set occurred, then unloaded and reloaded up to failure. Deflection controlled loading was used in the inelastic region. 3) Flexural cracks developed and turned horizontal at the steel deck level. Load-deflection curves matched analysis, though second tests were weaker due t
