Low cyclic loading tests were carried out for one precast two-way hollow slab shear wall with cast-in-situ boundary elements and one RC shear wall. The seismic performance of precast two-way hollow slab shear wall was analyzed. The test results indicated that macroscopic vertical cracks appeared along precast slab vertical holes of precast two-way hollow slab shear wall. The failure characteristics of the precast two-way hollow slab shear wall were significantly different from that of the reinforced concrete shear wall. Shear failure could be avoided and seismic performance of the new type shear wall was good.

Through exposure test of FRP-reinforced concrete member in littoral test area of temperate marine zone, the durability and constructional measures of FRP-reinforced concrete structure are investigated. The test results show that FRP shell on the surface of FRP-reinforced concrete member is effective in avoiding wave flush, freezing and thawing damage, preventing chloride ion corrosion and improving durability. On the other hand, reliable measures should be taken to protect concrete structures with no FRP shell on the surface. Based on above, the provided reference for evaluation durability of FRP-reinforced concrete structure, and proper constructional measures for FRP-reinforced concrete structure are presented.

The shear wall built with precast two-way hollow slab is an innovated precast concrete shear wall suitable for housing industrialization. Two shear walls built with precast two-way hollow slabs were tested pseudo-statically under low cyclic lateral loads to acquire their failure process and modes. The effect of the axial compression load was investigated. The study proved that vertical cracks along the vertical holes of the new type shear wall have been appeared to avoid brittle shear failure, and the shear wall developed integral section wall to walls-columns combination. As the results, the shear walls have the adequate deformability. The test results showed that with the increase of axial compressive ratio, crack development has been limited and the energy dissipation capacity has been improved. It also can be found that with the increase of the axial compressive load, shear capacity of the new type shear walls have been improved.
