| Abstract: | The paper firstly investigates the types and causes of the temporary construction joint in cast-in situ concrete structure. Then, the problems and solutions for the design and construction of post-pouring concrete strips were discussed. Moreover, the impacts of horizontal construction joints of the wall and column elements on their shearing resistances and nodal strength were given detailed investigation. Finally, the solution was proposed to deal with the construction joint from the viewpoint of structural design. |
