In the present study, the effect of core on shear lag phenomenon in tubular structures is investigated. Three different tubular structure models including model without core, model with central core and model with central core but eliminated in last 15 stories have been analyzed. A shear lag index is defined for evaluating these models. From examination of the results, the effective influence o...

A dual passive control system is proposed for high-rise buildings. Since the proposed system needs a substructure supporting the main building, it is usually used in high-rise residential apartment houses where a parking tower is used as the substructure. This new system consists of a base-isolation system and a building-connection system. While base-isolated buildings and interconnected buildi...

In recent years, Great development have been happened in the damping technique for high-rise building structure, how to build a structure which can ensure the safety of buildings in the sudden earthquake and how to adopt a new system structure which is more safe, more reasonable and more effective plays a decisive role in reducing earthquake disaster.This paper introduces the architectural stru...

High-rise buildings are commonly built in densely populated countries or urban areas. A balanced floor construction cycle is critical for construction of the frame structures. The objectives in scheduling the floor cycle are to ensure smooth flows of resources and to optimise the use of formwork and other materials. The floor area is usually divided into zones to allow the labour force and form...

Recent design of buildings utilizes different strategies to mitigate the lateral displacement and acceleration from wind and earthquake excitation. One of the strategies is to dissipate external energy with dampers. For high-rise buildings, outrigger systems which connect the core and perimeter columns are innovative system, which to combine stiffness of both the core and perimeter columns to r...
