Noticeably, the design of today’s building particularly high rise building and skyscraper show irregularity in both horizontal and vertical direction which is dangerous for each element inside the building. Handily, certain disjoint can be applied to the building to minimize the irregularity for better desired behaviour. Dilatation is a well-known method together with several other methods are introduced and implemented for gaining principal of simple regular building. Double column and cantilever beam method are two of them which are excellent to divide the building into several regular buildings after they are applied. The double column is found out to perform better on dilatation direction application at the weak axis of the building. Moreover, accurate review of double column distance will solve the load transfer discontinuity so that better behaviour and performance can be satisfied. Hereinafter, the cantilever beam conducts perfectly when the shear wall is sufficiently installed and the cantilever beam span is contently fulfilled. Shear wall remarkably contributes to enhancing the behaviour and performance of the structure as the shear wall placement is proper to absorb seismic lateral force. Recommendation of both systems can be well performed once the column distance, cantilever span, and shear wall installation are strongly taken into consideration.

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.

Hybrid ventilation is an effective approach to reduce cooling energy consumption by combining natural and mechanical ventilation. Previous studies of full-scale whole-building measurements of high-rise hybrid ventilation are quite limited due to the complexities of buildings and variable ambient conditions. As a result, validated and accurate whole-building simulations of hybrid ventilation often cannot be found in the literature. This paper reports a series of full-scale measurements of hybrid ventilation in a 17-storey high-rise building and associated whole-building simulations by 15-zone detailed and a 5-zone simplified multizone models. The paper is one of the first studies of using multizone models and real-world full-scale data and sharing key operational and performance experience and case studies of high-rise hybrid ventilation. Both the test data and the validated simulation models can be used for the comparison and validation of simulation models. The 5-zone simplified model developed from this study was able to model such a complex high-rise building by only a few zones, making possible the on-line model predictive control of a high-rise building. This was illustrated in this paper by an example of optimizing the uniformity of the hybrid ventilation on different floors by modifying inlet areas.

<p>This paper describes the method of structural design of a plate-like ultra high-rise building, taking the Shinjuku Toho Building as an example. In particular the major problems in the structural design of this building are described, namely ensuring safety during earthquakes, ensuring habitability during strong winds, and ensuring the load resistance of the columns that are subject to large axial forces. Also, the test results and performance of an "improved non-scallop method" for beam- column joint are described. Finally the method of structural designing "Godzilla’s Head" is described.</p>

Shear wall is the main component that resists the lateral force for high-rise buildings. With the rapid development of high-rise buildings, especially the super high-rise buildings, requirements for seismic performance of shear walls have become more sophisticated. This introduction summarizes the commonly used in embedded development and existing problems of steel plate shear wall, which are stiffened steel plate shear wall, non-stiffened steel plate shear wall, composite steel plate shear wall, preventing buckling of steel plate shear wall and low yield point steel plate shear wall.

Framework-shearwall structure is a dual resistive system to lateral force, which should have reasonable arrangement of shear wall thickness and quantity. The thickness should be decreased successively along the height of a building so as to adjust the internal force and deformation of the framework and the shear wall, and give full play to each of their advantages under stresses and finally achieve the purpose of safety and economy.
