The dynamic response analysis of the multi-body system with floating base includes the interaction between bodies and flow field as well as the one inside the multi-body system, which needs to use both the time-domain theory about the interaction between the object and the flow field and the method of multi-body system dynamics. With the growing complexity of the upper body, the multi-body system with floating base, whose generalized modeling and analysis become an inevitable trend.Using ADAMS(Automatic Dynamic Analysis of Mechanical System) for multi-body system dynamics analysis has unique advantages. It integrates modeling, solving and visualization technology. It also can realize automatically statics, kinematics and dynamics analysis. In this paper, the feasibility of ADAMS software and some related key issues are discussed, including the system architecture, fluid force analysis, fluid-structure coupling calculation module and ADAMS multi-body dynamics analysis module of data generation and transmission, etc.

We evaluated the performance of a high-rise residential building model in Purwokerto, Indonesia due to the seismic load. The evaluation was performed based on seismic loads given in the 2002 and 2012 Indonesian National Standard (SNI) using linear static analysis, dynamic response analysis and pushover analysis. Based on the linear static analysis, the drift ratio decreased by an average of 34.42 and 32.61% for the X and Y directions respectively. Meanwhile, based on the dynamic response analysis, the drift ratio also decreased by an average of 30.74 and 27.33% for the X and Y directions respectively. In addition, the pushover analysis indicates that the performance of this high-rise residential building model is still at Immediate Occupancy (IO) level. The post-earthquake damage state in which the building remains safe to occupy, essentially retaining the pre-earthquake design strength and stiffness of the structure. The risk of life-threatening injury as a result of structural damage is very low. Although some minor structural repairs may be appropriate, these would generally not be required prior to re-occupancy.
