Experimental Study on The Flexural Capacity of Cold-Formed Thin-Walled Composite Wall

To C galvanized thin-wall steel (or thin-walled steel tube) as the skeleton, fiber cement and lightweight concrete composite wall, for three pieces of full scale the wall specimen (Light steel keel + fiber cement board, light steel keel + fiber cement board + lightweight concrete, light steel keel + reinforced expansion net + lightweight concrete) the flexural bearing capacity study, got all kinds of wall shear bearing capacity and displacement performance metrics. The test results show that the cold-formed thin-walled light-steel composite wall has good integrity and strong bending capacity, and the addition of light-steel keel significantly improves the ductility of the composite wall.
