Precast concrete structure has been increasingly used all over the world. Its seismic performance has always been the key factor of its application in earthquake‐affected zones, especially in China. A new precast concrete shear wall structure using grouted lap splice connection and cast‐in‐place concrete was proposed in this paper. Low‐cyclic reversed load testing was conducted on a one‐half scale...
New precast concrete (NPC) shear wall consists of upper and lower prefabricated wall panels connected with reservation connection reinforcements inserted in the reserved galvanized metal bellows with full grout. The accomplished test results have demonstrated that the force mechanism of NPC shear wall is significantly different from that of traditional cast-in-situ concrete shear wall. To grasp the...
The assessment of the basic idea and technical details about the constructional quality of concrete structures in rural house based on the AHP and fuzzy comprehensive evaluation method are discussed. The assessment level system are designed according to the reference named the state standard “Code for acceptance of constructional quality of structures in rural house” which is compiling. Delphi-method,...
To be adapted for and promote building industrialization, the research of prefabricated rectangular open caisson working well during pipe jacking was carried out. In the background of the first open caisson working well, strain test was carried out on the cast-in-situ region and horizontal butt seam region of prefabricated structure. In the sinking working condition, anti-tensile checking of the prefabricated...
