一.防震缝 1.屋盖和楼盖中防震缝宽度按下式计算a=Δ_1+Δ_2+2(厘米)式中:Δ_1和Δ_2——在水平地震计算荷载下,防震缝两侧骨架的最大位移,如柱顶标高处的位移Δ=S/C式中:S——相应方向作用于骨架上的设计水平地震荷载,并视为静力作用于所计算的高度;C——相应高度的结构高度。 2.支承在建筑物骨架上的悬墙,其竖向防震缝宽度应为悬墙高度范围内骨架的相对位移加2厘米,即a=Δ+2cm 在每个区段高悬墙(最好采用带形窗)下部牛腿标高处,沿墙全长设水平防震缝,缝
1. Shockproof seams 1. The width of the shockproof joint in the roof and floor cover is calculated as follows: a=Δ_1+Δ_2+2(cm) Where: Δ_1 and Δ_2 - Under the horizontal seismic calculation load, the shockproof joints on both sides of the skeleton The maximum displacement, such as the displacement at the top of the column, Δ = S/C where: S - the design level seismic load acting on the frame in the corresponding direction, and is considered as static acting on the calculated height; C - the corresponding height The height of the structure. 2. For the curtain wall supported on the skeleton of the building, the width of the vertical shockproof joint shall be the relative displacement of the frame within the height of the curtain wall plus 2cm, ie a=Δ+2cm. Use a band window to lower the height of the bull’s leg, and set a horizontal shockproof seam along the entire length of the wall.
