Will the steel binding of shear wall jump?

The upper longitudinal reinforcement of the frame beam should run through the middle node, and the anchorage length of the lower longitudinal reinforcement of the beam should meet the design requirements. Stirrup hooks at the lap joint are staggered and bound in the beam, with stirrup hooks of 135 and straight part length of 10d. If the closed hoop is made, the length of one-sided weld is 5d.

In the tension zone, the end of the binding joint of Grade I steel bar should be hooked (Grade II steel bar can be hooked), and the lap joint should be fastened at the center and both ends. The positions of the joints should be staggered. When binding lap joints are used, the cross-sectional area of reinforced bar with joints accounts for the percentage of the total cross-sectional area of reinforced bar in any section with specified lap length, and the tensile area is less than 50%.

Requirements for setting shear wall reinforcement:

1, the shear wall can only have enough ductility in the bending working state, so the shear wall should be high and thin. If the shear wall is too long, it will form a low-width shear wall, which will be destroyed by shear, and the shear wall is brittle, which is not conducive to earthquake resistance.

2. When the space at the bottom of the shear wall structure is large and the shear wall can't completely land, it is necessary to adopt the frame-supported shear wall structure with the bottom frame-supported shear wall.

3. The shear wall bay is 6.0-7.0m, which is more economical and reasonable than the small bay of 3.0-3.9m, which reduces the material consumption and increases the building area.
