摘要:
为了更好地实现绿色节能建筑设计与建设,提出基于BIM技术的低层建筑环境振动特性分析方法。利用BIM技术进行建筑建模：导入场地环境信息,并构建关联模型;对建筑设计方案进行设计;制定建筑工程的BIM方案文档、模型建立计划和碰撞检测,并深化节点详图,对管线进行检查。以某市交通枢纽高铁站为测试点,结合BIM建筑集成建模和地铁列车行驶振动计算分析对测试地点进行建模等操作。利用信号采集设备INV3020D、超低频振动信号拾振器等实验仪器和设备获取实验数据,根据实验数据经测试可知：列车荷载下,各个测点振动响应信号表现出了十分显著的周期特性与持续特性,持续时间大致为5s到25s,时间大约为20s;无论是加速度振动,还是速度振动,不同响应地铁列车所引起的建筑架构环境振动频率大致集中在20Hz至80Hz。
Abstract:
In order to better realize the design and construction of green energy-saving buildings,a method for analyzing the environmental vibration characteristics of low-rise buildings based on BIM technology is proposed. The paper uses BIM technology for building modeling: importing site environmental information and building associated models; designing architectural design plar; developing BIM plan documentation,model building plan and collision detection for building engineering,and deepening node details to inspect pipelines . Taking the high-speed railway station of a city transportation hub as a test point,combined with BIM building integration modeling and subway train running vibration calculation analysis,the test site is modeled. The experimental data were obtained by using the signal acquisition equipment INV3020D,ultra-low frequency vibration signal pickup and other experimental instruments and equipment. According to the experimental data, it can be seen that under the train load, the vibration response signals of each measuring point show very significant periodic characteristics and continuous characteristics. The duration is about 5 s to 25 s, and the time is about 20s. Whether it is acceleration vibration or speed vibration, the environmental vibration frequency of the building caused by different response to subway trains is roughly concentrated at 20 Hz to 80 Hz.
