摘要
对北京市某穹顶钢结构羽毛球馆的抗震性能进行分析,按照1∶10的比例制作了该羽毛球馆的模型,利用清华大学模拟地震振动台进行模型试验。试验采用环境激励和人工正弦激励两种方式进行加载,通过试验测得该模型在地震波作用下的振型、自振频率和阻尼比。在模型上安装加速度计、应变片等传感器测得模型在动载作用下的应变响应、位移、加速度和响应变化规律等。对试验数据进行分析,得知在8度地震作用下,该结构处于材料的弹性阶段,说明该结构的抗震性能较好。
In order to analyze the seismic behavior of a dome-shaped badminton stadium in Beijing,a model of the badminton stadium was established according to the scale of 1∶10,and the model test was conducted by using the simulated seismic station of Tsinghua University. In the experiment,environmental excitation and artificial sinusoidal excitation were exerted the model. The vibration mode,natural frequency and damping ratio of the model under the action of seismic waves were measured experimentally. In the model,accelerometers,strain gauges and other sensors were used to measure the strain response, displacement, acceleration and response of the model under dynamic load. The analysis of the experimental data showed that the structure was in the elastic state of the material under the seismic intensity of 8 degrees,which showed that the structure had better seismic behavior.
