Based on compressive test of twenty-two grouted masonry specimens and three reinforced masonry walls, the failure characteristics, the compressive strength of grouted masonry and compressive bearing capacity of reinforced masonry walls are studied, and the calculating formula of compressive strength of grouted masonry and axial compressive bearing capacity of reinforced masonry are proposed.

Then the calculation formula for axial compression bearing capacity of the shape-steel reinforced concrete special-shaped columns is suggested for design.

The experimental results indicate that the axial load strength of a circular tube confined concrete stub column is greater than that of a CFT column with the same parameters,while there is little difference on the ductility of the two kinds of columns.

The experimental results indicate that the axial load strength of a steel tube confined concrete stub column is greater than that of a CFT column with the same parameters when D/t is 70, while the axial load strength of a square tube con.

The test results indicate that the height of separated tubes in a CTRC column affects little on the axial load strength and ductility of CTRC stub columns.
