Frequency variable TMD system is developed based on the conventional TMD system, which has multiple frequencies and thus merits of MTMD. Frequency variable TMD can effectively reduce the dynamic response of structure induced by its own frequencies. In this study, this technique is applied to dynamic analysis of high-rise building. The results show that frequency variable TMD system can optimize the dynamic response of the structure and control the vibration effectively, compared to conventional TMD system.

Various challenges should be considered in the development of an effective model for the planning and control of high-rise building construction. These challenges have been identified as results of the construction process. This paper discusses the engineering planning and management control in high-rise building construction. The methodology should also be able to address the concerns and considerations regularly faced in the industry and thus providing flexible modeling, which can be used by different levels of management

Two Alternatives

This paper deals with static and dynamic analysis of asymmetric high-rise building. Two alternatives have been analysed – without dilatation and with dilatation. Then, the influence of the dilatation was discussed. The building was located in 4th seismic area in Slovakia (Bratislava). The description of the building, applied load, considered soil-structure interaction, created calculating models, used analysis and obtained results are mentioned here. The conclusions and the photos of defective repairs of real structures are depicted at the end of the paper.

In order to solve the narrow range and control difficulties of the excited frequency in metal bar cropping with variable frequency vibration, the structure of the eccentric block in cropping machine was improved on in the paper and a new structure model of changing the integral eccentric block into one of main eccentric block and some small adjustable eccentric blocks, was also proposed. The key parameters of the cropping machine in the action of two different types of eccentric blocks were analyzed theoretically in detail. At the same time, the corresponding amplitude frequency characteristics of the cropping machine were also obtained. The cropping experimental results of 45 steel bar show that the cross-section quality and the cropping time are improved remarkably in the action of one main eccentric block and four adjustable eccentric blocks, comparing with the cropping results in the action of the whole eccentric block.
