The application of active multiple tuned mass dampers (AMTMD) for suppressing
translational and torsional responses is addressed for a simplified two-degree of
freedom structure, able to represent the dynamic characteristics of general
asymmetric structures subject to ground motions. By employing the developed
optimum parameter and effectiveness criteria of the AMTMD, the influences of
the normalized eccentricity ratio and the torsional-to-translational frequency
ratio of asymmetric structures on the optimum parameters and effectiveness of
the AMTMD are investigated in detail. For comparison purposes, the results of a
single active tuned mass damper also are taken into consideration
建筑信息模型(Building Information Modeling)或者建筑信息化管理(Building Information Management)或者建筑信息制造(Building Information Manufacture)是以建筑工程项目的各项相关信息数据作为基础,通过数字信息仿真模拟建筑物所具有的真实信息,通过三维建筑模型,实现工程监理、物业管理、设备管理、数字化加工、工程化管理等功能。它具有信息完备性、信息关联性、信息一致性、 可视化、协调性、模拟性、优化性和可出图性八大特点。将建设单位、设计单位、施工单位、监理单位等项目参与方在同一平台上,共享同一建筑信息模型。利于项目可视化、精细化建造。BIM不再像CAD一样只是一款软件,而是一种管理手段,是实现建筑业精细化,信息化管理的重要工具。
