［摘要］合理地應(yīng)用隔震技術(shù)可保證建筑在中、大震后的正常使用性能，對(duì)高烈度區(qū)體育館建筑具有較強(qiáng)的適用性。以唐山新體育中心體育館為例，對(duì)高烈度區(qū)體育館建筑進(jìn)行隔震設(shè)計(jì)研究。首先，對(duì)此體育館進(jìn)行剛性結(jié)構(gòu)方案和隔震結(jié)構(gòu)方案比選，以證明此體育館采用隔震結(jié)構(gòu)方案可減小構(gòu)件截面尺寸、增大建筑使用空間，同時(shí)降低工程造價(jià)。其次，著重討論了隔震層開(kāi)洞、黏滯阻尼器布置及其位置等問(wèn)題，通過(guò)在隔震層比賽場(chǎng)地區(qū)開(kāi)洞且沿洞口周邊布置黏滯阻尼器的方式，在實(shí)現(xiàn)經(jīng)濟(jì)性的同時(shí)保證隔震層的整體性，為帶比賽場(chǎng)地的體育館類建筑隔震設(shè)計(jì)提供參考。最后，詳細(xì)闡述此體育館隔震設(shè)計(jì)的主要計(jì)算結(jié)果，證明隔震技術(shù)在此項(xiàng)目中應(yīng)用的有效性和安全性。

Abstract:By reasonable application, seismic isolation technology can ensure the normal service performance of  building after fortification or rare earthquakes, and it has strong applicability to gymnasium buildings in high seismic fortification intensity areas. Taking Tangshan Gymnasium as an example, the seismic isolation structure design of the gymnasium building in the high seismic fortification intensity area was researched. Firstly, the rigid structural scheme and the isolation structural scheme of the gymnasium were compared, and it proves that the isolation structural scheme reduces the member section size, increases the architecture use space and decreases the cost. Secondly, the isolation layer opening, the arrangement and location of viscous dampers were mainly discussed. By setting openings at the playing field on the isolation layer and arranging viscous dampers around the openings, the economy was achieved while the integrity of the isolation layer was ensured, which could provide reference for the isolation design of gymnasium buildings with playing fields. Finally, the main calculation results of the seismic isolation design of the gymnasium were elaborated, proving the effectiveness and safety of the seismic isolation technology used in this project.

Keywords:high seismic  intensity area; gymnasium; base isolation; isolation layer opening; viscous damper; wind-resistant design; temperature effect
