In construction of each project requires resources in its completion. They are workers, costs, tools, methods, and materials. The process for achieving project purpose, have defined the boundary called triple constraints, are budget allocated, schedule, and quality. From these (triple constraint) in the project, productivity of labors are one of an important thing that give an effect in time project performance. This research is to analyze the effect of labor productivity in time project performance at high rise building, especially in Jabodetabek area. The type of data for this research use primary data, and for data analysis technique use a simple linear regression with SPSs v.24 as a software. The result is labor productivity give the effect significantly in time project performance. In other words, if the labor productivity higher than the time to complete all activities will be shorter, and vice versa.

The seismic performance of hypothetical low and high-rise steel framed structures founded on both soft and stiff soils in Mexico City and equipped with (i) friction damping devices, (ii) base isolators and (iii) a combination of base isolators and friction damping devices is compared. The response of the three structural systems, including soil- structure interaction, is examined for two specific sites in Mexico City: the stiff hills zone and the soft lake bed zone. The results of the study show that although soil-structure interaction can be beneficial for some base isolated structures, friction damping alone provides a more consistent way of protecting structures in Mexico City against earthquakes.

In order to overcome the problems of long analysis time, low accuracy and high energy consumption in traditional lateral vibration analysis methods of high-rise buildings, a new method of lateral vibration analysis of high-rise buildings based on partial differential equation is proposed. Based on Hamilton's principle, the partial differential equation of lateral vibration of high-rise buildings is established, and the Galerkin method is used to solve the partial differential equation until the discrete solution is obtained, and then the displacement response of high-rise buildings under different excitation frequencies is obtained. The experimental results show that compared with the traditional method, the proposed method has the advantages of short calculation time, high accuracy and low energy consumption.

Multiple Tuned Mass Dampers

Multiple tuned mass dampers (MTMDs) distributed along height of a high-rise building are investigated for their effectiveness in vibration response control. A 76-storey benchmark building is modeled as shear type structure with a lateral degree of freedom at each floor, and tuned mass dampers (TMDs) are installed at top/different floors. Suitable locations for installing the TMDs and their tuning frequencies are identified based, respectively, on the mode shapes and frequencies of the uncontrolled and controlled buildings. Multimode control strategy has been adopted, wherein each TMD is placed where the mode shape amplitude of the building is the largest or large in the particular mode being controlled and tuned with the corresponding modal frequency. Newmark’s method is used to solve the governing equations of motion for the structure. The performance of the distributed MTMDs (d-MTMDs) is compared with single tuned mass damper (STMD) and all the MTMDs placed at top floor. The variations of top floor acceleration and displacement under wind loads are computed to study the effectiveness of the MTMDs in vibration control of the high-rise building. It is concluded that the d-MTMDs are more effective to control wind induced vibration than the STMD and the MTMDs placed at top floor.
