The design utilizes the prestressed tendons to enable the structure to have good self-resetting capability in the earthquake, and the residual displacement is reduced. The prestressed tendon adopts the design of stretching after unbonded, the prestressed tendon pore channel is pre-embedded in the swing wall base body, the prestressed tendon anchorage devices are pre-arranged at the foundation and the wall top of the swing wall base body, the prestressed tendon passes through the pore channel pre-embedded in the wall body and is respectively anchored at the wall body top and the foundation, and the anchoring at the wall top can ensure that the internal stress of the prestressed tendon is increased in the process of opening gaps of each swing surface when the swing wall body swings, so that better restoring force is provided for the swing wall body.
In the design, the shearing resistance design of the pre-embedded steel bar and the pre-embedded steel cap is adopted for the swinging node between the adjacent swinging surfaces, so that the steel bar is still ensured to be inserted into the steel cup in the swinging process of the wall body, the shearing resistance effect is achieved, the pre-embedded steel bar and the pre-embedded steel cap are arranged in the middle of the swinging wall base body to form the swinging node, the internal force of the swinging wall body is reduced, the design requirement is reduced, and meanwhile, the risk of wall body damage caused by longitudinal rib yielding in a large earthquake is reduced; the size that the rod iron inserted the steel cap and the bore of steel cap design according to swaing the wall biggest design value that sways, guarantee that the wall body still can combine together with the steel cap when taking place the biggest and sway, reach the effect that shears, guarantee that the wall body all has better shearing ability in the face and off-plate, guarantee the stable rocking of wall body emergence in the vertical simultaneously.
The design can be applied to the new common building structure to improve the shock resistance of the structure, and can also be used for the shock resistance reinforcement of the existing building structure. In use, the wall body of the swing wall to be designed is connected with each layer of the frame structure through the horizontal connection node, the bottom of the swing wall is connected with the foundation, and the deformation between layers of the frame structure is controlled through the swing wall in an earthquake to improve the shock resistance of the original frame structure.
The segmented self-resetting swinging wall can reduce the seismic response of the whole structure and effectively reduce the shear force of the base of the structure. The self-resetting capability of the wall body can be improved by arranging the prestressed tendons on the swinging wall, but the lateral stiffness of the structure is also increased, so that the shearing force of the structure base in the earthquake is improved. The method for processing the swing wall in a segmented manner weakens the integrity of the wall body, avoids the situation that the rigidity of the whole structure is improved too much due to the addition of the whole section of the swing wall, and can effectively reduce the rising amplitude of the shearing force of the base of the whole structure after the addition of the swing wall.
The segmented self-resetting swinging wall can effectively reduce the internal force of the swinging wall body in an earthquake. The swing wall has the advantages that the swing surface is additionally arranged in the middle of the wall body, so that the whole wall body is divided into two or more wall sections, namely the swing wall base body can effectively reduce the internal force, the maximum bending moment and the maximum shearing force of the wall body, reduce the strength and rigidity requirements of the swing wall, avoid the damage and the loss of the effectiveness of the wall body at the position where the stress of the wall body is large in advance, and be beneficial to realizing the damage of the swing wall in an earthquake, thereby prolonging the service life of the swing wall.
This wall is swayd from restoring to throne to segmentation can effectively reduce the interlaminar displacement of structure top floor. Although it is more even to let the interbedded deformation distribution of each floor of overall structure to the additional whole section of frame construction wave wall, nevertheless also can lead to the unexpected grow of displacement between the structure top floor, this is to structure top floor and unfavorable, especially to adopting the existing structure that the wall was consolidated of swaing, because design conditions such as the arrangement of reinforcement of each floor of existing structure have been confirmed, the beam column cross sectional dimension and the arrangement of reinforcement of top floor are often little than the lower part floor, when displacement between the top floor increases, probably lead to top floor beam column to go out the hinge condition and aggravate, if the column end appears in the plasticity hinge more, still probably form new weak layer at the top floor, be unfavorable for the structure antidetonation. After the swing wall is subjected to segmentation treatment, the interlayer displacement of the floor where the upper wall section is located can be reduced, and the situation that the top floor is seriously hinged can be avoided.
This design is to swaing the wall body and segmenting, can effectively reduce prefabricated wall of swaing in the difficulty of transportation and hoist and mount construction. Due to the particularity of the wall body of the swinging wall, the wall body is usually prefabricated in advance, the swinging wall is combined with the prefabricated assembly type technology, so that the application prospect is wide, and the difficulty in transportation and hoisting caused by overlarge wall body size in the prefabrication and installation processes can be avoided by segmenting the wall body.
