The dilatation of the high-rise building by inserted field is the main topic of this paper. This building contains of two “towers” with different heights (8-storey and 25-storey), which are linked by inserted field. The description of the building and applied loads are shortly mentioned. The paper is mainly focused on the importance of the dilatation and its types, the modelling of inserted field and its structural solutions. The comparisons of horizontal forces due to the wind load and seismic load are presented at the end. The solution was recalculated for four seismic areas in Slovakia, where different values of basic seismic acceleration ar are. Also, the maximum horizontal deflections calculated for three alternatives of the building (without dilatation, with continuous dilatation 50 mm located between two “towers” passing through the foundation, with dilatation by inserted field between two “towers”) due to static wind load are presented here.

Load Conditions

Shear wall system is used as one of the most lateral load resisting systems in mulit-story building. Shear wall is quite effective in resisting wind and seismic load in medium-rise and high-rise building. Shear wall provided high stiffness and strength, which can be used to resist large lateral as well as vertical load, making the performance of the building beneficial in various wind load conditions. This study has been focused on the displacement of the different lateral load resisting system for high-rise buildings under various wind load conditions. In this paper, a study was carried out by changing the locations of shear wall radically to determine the structural configuration of a multistory building accordantly. This study has been focused on the effect of addition of shear wall at different location and configuration in buildings without shear wall as well as with shear wall. Besides that, from the software results, the behavior of the shear wall with and without opening was able to observed by obtaining the lateral displacement when acted by 10kN point load at the top left of the wall. The accuracy of the software was able to verify by comparing the result obtained from ETABS and SAP2000 and it was found that the percentage difference between values obtained from that two software is below 20 percent. The maximum lateral displacement at 40m/s and 50m/s is 1.8 and 2.8 times bigger than maximum lateral displacement at 30m/s respectively. The lateral displacement of the shear wall increases as the opening size increases.

The lateral load-resisting system of high-rise buildings in regions of low and moderate seismicity and strong wind such as the typhoon in the Korean peninsula considers the wind load as the governed lateral force so that the practical structural engineer tends to skip the evaluation against the seismic load. This study is to investigate wind-designed steel diagrid buildings located in these regions and check the possibility of the elastic design of them out. To this end, first, the diagrid high-rise buildings were designed to satisfy the wind serviceability criteria specified in KBC 2016. Then, the response spectrum analyses were performed under various slenderness ratio and wind exposures. The analyses demonstrated the good seismic performance of these wind-designed diagrid high-rise buildings because of the significant over-strength induced by the lateral load-resisting system of high-rise buildings. Also, the analysis results showed that the elastic seismic design process of some diagrid high-rise buildings may be accepted based on slenderness ratios in all wind exposures.

In this paper, the object-oriented method is used to study the pre-processing system of 3D high-rise building steel structure CAD. For the high-rise building steel structure design optimization system, users mainly contact with the functions of modeling, analysis, design checking and drawing. In fact, all these functions are carried out around the data stored behind. Three-dimensional high-rise building steel structure CAD pre-processing subsystem mainly integrates three-dimensional entity construction module, node design and editing module, construction drawing, processing drawing and CNC data output module. In this paper, the wall element is used to simulate the shear wall element, and the wall element can be automatically refined into a shell element composed of quadrilateral membrane element with rotational degree of freedom and generalized conforming bending plate element for thick and thin plate, which improves the speed and accuracy of analysis and calculation of shear wall. Various loads of high-rise building are calculated, especially the wind load of space action. It provides a new idea for wind load calculation of high-rise buildings. It is better to put forward a practical system optimization model, which can deal with the objective function, variables and constraints in a large number of engineering processing, and consider the actual constraints as fully as possible, which has strong practicability.
