Contact Mr.Tang 24-hour hotline telephone 0318-5821892 15333180470 joints Seismic Joint summary should be based on seismic intensity, height and elevation case structure material type, structure type, structure elements, there is sufficient width, on both sides of its upper structure should be completely separated. When setting the expansion joints and settlement joints, the width should be consistent with the requirements of earthquake-resistant joints. Gravity retaining wall should be set at intervals of 10 ~ 20m expansion joints together, when there is a change of local groups should be added Settlement Joint. Retaining structure in the corner, measures should be taken to strengthen the structure. High-rise building of concrete structures should be set Seismic Joint meet the following requirements: 1 Seismic Joint width should meet the following minimum requirements: frame houses, no more than part of the 15m height, desirable 70mm, part of more than 15m, 6 degrees, 7 degrees, 8 degrees and 9 degrees corresponding increase in height every 5m, 4m, 3m and 2m, should be widened 20mm; 70% 2 frame shear wall structure according to the first paragraph of housing values ??using shear wall structure according to the first paragraph of house value of 50% used, but both are not less than 70mm. Earthquake architecture is not the same joints on both sides, slit width shall adverse shock structure type determination; shock joints on both sides of the house is not the same height, the height shall be determined shock slit width lower house. When there is a big difference between the basis of the settlement of adjacent structures, should increase the width of the slit shock. Seismic Joint house full height should be set up along the basement foundation undefended shock can sew, but in correspondence with the upper shock at the seam should strengthen the construction and connection. If there is no reliable measure of structural units or between the main building and the podium, we should adopt the practice of setting bracket joists shock seam.
