Earthquake isolation substructure for reducing earthquake acceleration in local room
The invention discloses a seismic isolation substructure for reducing the seismic acceleration of local rooms, the seismic isolation substructure is formed by integrally connecting a plurality of upper and lower layers of rooms at the same position in a main body structure, and the bottom of the seismic isolation substructure is supported on a frame beam of the main body structure through a seismic isolation support; a seismic isolation gap is formed between the seismic isolation substructure and the vertical face of the main body structure, a viscous damper is arranged between the seismic isolation substructure and the main body structure in the horizontal direction, a seismic isolation layer is formed between the lower layer of the seismic isolation substructure and the main body structure, and steel springs are arranged in the seismic isolation layer in the vertical direction and correspond to important equipment. Equipment room structural members at the same position of different floors in the space of a building are connected to form the space seismic isolation and reduction substructure relatively separated from the main body structure, so that the floor acceleration of the rooms in the seismic isolation substructure under an earthquake can be effectively reduced, and the requirements of acceleration sensitive important equipment are met; and the economic cost is higher.
本发明公开了一种降低局部房间地震加速度的隔震子结构，所述隔震子结构由主体结构中相同位置的上下多层房间连接成整体构成，所述隔震子结构的底部通过隔震支座支撑在主体结构框架梁上，所述隔震子结构与主体结构立面之间设有隔震缝，所述隔震子结构与主体结构之间在水平方向上设有粘滞阻尼器，所述隔震子结构的下层与主体结构之间形成有隔震层，所述隔震层内与重要设备相对应的位置处沿竖直方向设有钢弹簧。本发明通过将建筑中空间上不同楼层相同位置的设备房间结构构件相连形成与主体结构相对脱离的空间减隔震子结构，可以有效降低地震下隔震子结构内部房间的楼层加速度，从而满足加速度敏感重要设备的要求，具有更好的经济成本。
