摘要:
提出一种新型调谐液体阻尼器——内置横向挡板的调谐液体阻尼器(TLDEB)。通过在普通调谐液体阻尼器(TLD)装置中设置横向挡板,使液体绕流时产生附加阻尼来增强其耗能作用,以改善TLD对高层建筑的减振效果。结合经典势流理论以及能量耗散原理推导了TLDEB的等效位移、附加阻尼比,并对其进行了等效线性化。以某实际高层建筑结构作为算例,通过对地面随机激励和地震波激励的数值仿真来验证TLDEB的减振效果。结果表明:TLDEB可有效地增大结构阻尼,具有比普通TLD更优良的减振控制效果。
Abstract:
A new tuned liquid damper device, tuned liquid damperembedded baffles(TLDEB), was proposed to increase energy dissipation through setting transverse baffles in a common tuned liquid damper(TLD)device. The proposed TLDEB was expected to achieve a better control performance for a high-rise building under earthquakes than an common TLD. The equivalent displacement, additional damping ratio and its equivalent linearization of a TLDEB were formulated by using classic potential-flow theory and principle of energy dissipation. A real high-rise building structure was used as a numerical example to demonstrate the damping effectiveness of the proposed TLDEB system subjected to ground random excitation and earthquake wave excitation. The results indicate that TLDEB is capable of improving the structural damping and it has more excellent damping effectiveness than common TLD.
