The existing technique of construction of the time was using concrete with a plain straight steel in the center of a concrete beam. The steel in the concrete would slip if there was even the tiniest bit of room between the hardened concrete and the steel and it would break adhesion. The main reinforcing bar had plain steel beam members rigidly attached to it. This diagonal tension fractured the reinforcing bar beams since the adhesion was broken. This caused weakness in the concrete/steel reinforced beam and a failure that could cause catastrophic results. The problem was that the plain steel beam separated from the concrete causing a failure since the two materials were no longer working together for strength."@en }
