Failure Mechanism of Foam Concrete with C-Channel Embedment

Forty-eight tests have been carried out to find of the failure mode of a new type of the foam concrete using C-Channels as embedements. Four groups of foam concrete specimens with various embedment depths of the steel in the concrete. The modes of failure of this new type of structure are summarized, which include the independent failure of the C-Channels with and without a concrete block inside the channel as well as the combined failure of the two channels, and the failure of the extrusion block. It is concluded that the failure involves independent slippage between two C-Channels, and the steel and the foam concrete blocks inside the C-Channels. (Author)
