Assembly light steel tube frame with recycled concrete-thin wall was proposed

which was suited for lower or multilayer floors farmhouse. Assembly frame was assembled by recycled concrete filled light steel tube beams and columns

and light wall adopted single row of steel bars and recycled concrete. Frames and walls were connected by bolts. The frame bears the vertical load and resists the horizontal load with walls together. Pseudo-static tests on 4 assembly light steel frame-thin wall and 1 single frame were conducted to study the influence of reinforcement spacing and the wall thickness on the joint work performance of frames and walls. Failure modes

hysteresis property

load-carrying capacity

ductility

stiffness and energy dissipation capacity of specimens with different bar spacing and wall thickness were analyzed. The results indicate that light steel frame-thin wall distinctly has two seismic defensive lines and works together well. The failure modes of walls are the shear failure and the frame are the axial-flexural failure

respectively

which indicate that the assemble components are safe and reliable and the structure has adequate ductility. Reducing spacing of bars or increasing thickness of the wall can improve ductility and dissipation capacity of specimens.
