Stable Shape

Recent Years, Many high rise buildings are being constructed across the world due to the increase in population. From the design point of view, lateral load such as earthquake and wind load should be taken into consideration while designing process. Architectural design of buildings sometimes leads towards difficult and unusual shape that challenges structural designers. The objective of this study is to assess the building behavior when subjected to wind load. To achieve this objective, different shapes of building such as pentagonal, triangular and circular building are assessed for stability. Parameters such as storey drift and lateral displacement are considered in order to find most effective and stable shape. The computer program ETABS is used for analysis. As the height of the building increases, wind load effect becomes significant and should be considered for designing. This could also be achieved by selecting most stable shape and appropriate structural system for tall buildings.

Abstract High-rise buildings in big cities are crucial for business, economic, educational, residential, and entertainment activities in recent times. The technology discoveries in various fields that support high-rise building construction such as structure, mechanical, electrical, and materials have opened up opportunities for comfortable and environmentally safe architectural work. The first milestone of high-rise building construction knowledge in Indonesia was the completion of the thirteen-floors Sarinah retail building in 1967. Indonesia, especially in Jakarta, then experienced rapid growth of high-rise buildings construction. However, there is limited research on the development of high-rise building designs in Indonesia, especially from an architectural design perspective. It leads to the lack of literature on high-rise building design in Indonesia. By utilizing a publicly accessible database from the Council of Tall Buildings and Urban Habitat and recent literature called Designing Tall Building by Mark Sarkisian, this paper explores the design development of high-rise buildings in Jakarta from time to time in the aspects of architecture, structure and sustainability.

The impression of blast load on building is very important things to consider in a design process. A bomb detonation within structures or straightaway the building can drive damage on the building either in external or internal structural frames, by collapse of walls etc. These kinds of affliction are uncommon and man-made disasters. The impact of blast load is equivalent to a dynamic loads and that demand to take caution while calculating of it. Someone can calculate as other lateral forces like earthquake and wind load. Design fully blast resistant structures is not pragmatic and economic, till the knowledge of mitigating its effect while designing new structures or maintaining old one with its less impact is identical. In this present study, the behavior of G+15 storey RCC structure is analyzed under the blast load with the help of ETAB software. According to the IS code provision, the dead load, live load and wind load has been considered to study the effect of it. Also, the distance of blast and its charge weight is very according to IS 4991-1968.

Due to the shortage of land in cities and population growth, the significance of high rise buildings has risen. Controlling lateral displacement of structures under different loading such as an earthquake is an important issue for designers. One of the best systems is the diagrid method which is built with diagonal elements with no columns for manufacturing tall buildings. In this study, the effect of the distribution of the tuned mass damper (TMD) on the structural responses of diagrid tall buildings was investigated using a new dynamic method. So, a diagrid structural systems with variable height with TMDs was solved as an example of structure. The reason for the selection of the diagrid system was the formation of a stiffness matrix for the diagonal and angular elements. Therefore, the effect of TMDs distribution on the story drift, base shear and structural behaviour were studied. The obtained outcomes showed that the TMDs distribution does not significantly affect on improving the behaviour of the diagrid structural system during an earthquake. Furthermore, the new dynamic scheme represented in this study has good performance for analyzing different systems.

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.

Introduction. The article is devoted to the description of the method of experimental modeling of wind effects on buildings and structures located in dense urban areas. The relevance of the research topic is explained by the increase in the density of urban development in large cities, as well as the tendency to the point construction of high-rise buildings in areas with existing low-rise, historical buildings. Materials and methods. Experimental modeling in a wind tunnel is considered as a research method. Studies were conducted on a reduced geometrically similar model of the real object. As measuring equipment was used the research system, which based on differential strain-gauge pressure sensors. The results of experimental studies are presented in the form of dimensionless aerodynamic pressure coefficients. The object under study is a building consisting of three non-high-rise and one designed high-rise buildings. In order to assess the impact of the designed building on the wind load on the existing building structures, three different schemes of their location were considered. Results. Parameters of wind load (aerodynamic coefficients) on existing building structures were determined and exponential graphs of the dependence of the average values of the aerodynamic coefficients on the location of the height structure and the angle of attack of the incident air flow were constructed. Conclusions. The results of the research suggest a significant decrease in the average wind load on the buildings of the existing building when the high-rise building is located near it, which indicates the beneficial effect of this arrangement of buildings on the aerodynamic situation of the area in terms of wind load on the buildings themselves. Nevertheless, at the stage of development of project documentation for each such facility, it is recommended to conduct comprehensive studies, where, in addition to the wind load, the impact of the designed structures on the aeration and bioclimatic comfort of the development area will be assessed.

Outrigger structural systems are quite effective using the lateral loads on tall buildings, one of the main benefits of utilization outrigger is that it can reduce deformation and the danger of inter-story drift caused by lateral loads acting on the building. In this case, wind loads will be viewed as a lateral load because the wind load acting on tall buildings can also cause deformation of the building. The implementation of the outrigger system is viewed from different positions to see the deformation that occurs and the placement of the maximum location. The results of the analysis of wind loads reviewed on these buildings have proven that the use of outriggers in buildings can reduce displacement by 19.58%, and inter-storey drifts by 13.24%, which is applied in a position of ½ of the building height. The optimum location of the outrigger installation can also be determined by calculating the analysis of the maximum deflection that occurs on the 40th floor.
