Earthquake Resistance. Earthquake-resistant structures are structures designed to withstand earthquakes. While no structure can be entirely immune to damage from earthquakes, the goal of earthquake-resistant construction is to erect structures that fare better during seismic activity than their conventional counterparts.

The invention relates to a hollow floor system filled with an air-filling bag and a construction method thereof, belonging to the field of the structure of the common building. The hollow floor system consists of the air-filling bag (1), upper steel bars (2), lower steel bars (3), hidden girder steel bars (4) and concrete (5), wherein the air-filling bag (1) is positioned among the upper steel bars (2), the lower steel bars (3) and the hidden girder steel bars (4); a bag wall (8) of the air-filling bag (1) consists of four side walls (9), an upper wall (10) and a lower wall (11); the shapes of at least two side walls (9) adjacent to the hidden girder steel bars (4) in the air-filling bag (1) are planes; the shapes of the upper wall (10) and the lower wall (11) are heaved-outward arc surfaces; and positioning pieces (12) are arranged among the inner sides of the side walls (9) so as to ensure that the two side walls (9) are parallel mutually. The hollow floor system has large span, better reliability, earthquake resistance and crack resistance, and good economy and applicability.

Concrete buckling-proof steel plate shear wall for bottom strengthening zone of steel structure dwelling

ActiveCN107700696AImprove shear resistanceImprove bearing capacityConstruction materialWallsEarthquake resistanceSheet steel

The invention provides a concrete buckling-proof steel plate shear wall for a bottom strengthening zone of a steel structure dwelling. The concrete buckling-proof steel plate shear wall comprises a concrete buckling-proof cover plate and a steel plate wall provided with vertical stiffened ribs; the concrete buckling-proof cover plate is arranged on the outer side face of the steel plate wall provided with the vertical stiffened ribs, so that all cover plate bolt holes are concentrically aligned with corresponding steel plate wall bolt holes; and the tail ends of bolts sequentially penetrate through the steel plate wall bolt holes and the corresponding cover plate bolt holes, and nuts are screwed at the tail ends of the bolts. The concrete buckling-proof steel plate shear wall has the advantages that the concrete buckling-proof cover plate is installed on the outer side of the steel plate shear wall through the bolts, and by adjusting the hole diameter of reserved bolt holes of the concrete buckling-proof cover plate, it is ensured that relative slip can be generated between the steel plate shear wall and the concrete buckling-proof cover plate when the lateral force of the wall reaches a certain value, appearance of a tensile force band of the steel plate shear wall can be delayed due to existence of the concrete buckling-proof cover plate, and the shearing ability, the bearingcapacity and the earthquake resistance ability of the steel plate shear wall can be improved accordingly.
