Experimental Investigation on the Structural Behavior of Double Channel Castellated Steel Beams

The main idea of castellated steel beams is to reduce their weight by creating void space (web holes) in the main beam body. This structure tends to exhibit superior properties such as advanced strength, lightweight, and cost-saving compared to the amount of steel used compared with reference beam w...
