Building Shape

A study of approach aerodynamic shape optimization of a high-rise building, Shenzhen Kingkey financial tower, was performed in a boundary layer wind tunnel at Shantou University. Building shape has significant effects on the wind load forcing on the structure. The peak overturning moments about x-axis and the peak accelerations at the top of building are presented in this paper. Compared with the experimental results, one case is considered as the optimal case for structural design.

Interval Analysis Method

The traditional wind-induced response analysis of high-rise buildings conventionally considers the wind load as a stationary stochastic process. That is, for a certain wind direction angle, the reference wind speed (usually refers to the mean wind speed at the building height) is assumed to be a constant corresponding to a certain return period. Combined with the recorded data in wind tunnel test, the structural response can be computed using the random vibration theory. However, in the actual typhoon process, the average wind speed is usually time-variant. This paper combines the interval process model and the nonrandom vibration analysis method with the wind tunnel test and proposes a method for estimating the response boundary of the high-rise buildings under nonstationary wind loads. With the given upper and lower bounds of time-variant wind excitation, this method can provide an effective calculation tool for estimating wind-induced vibration bounds for high-rise buildings under nonstationary wind load. The Guangzhou East tower, which is 530 m high and the highest supertall building in Guangzhou, China, was taken as an example to show the effectiveness of the method. The obtained boundary response can help disaster prevention and control during the passage of typhoons.

Wall Element

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.

The Impact

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.
