Module equivalent frame method for structural design of concrete high-rise modular buildings

Microcomputer finite element analysis of reinforced concrete slab systems can now be routinely performed to produce realistic numerical simulation of three-dimensional structural behaviour. However, an efficient use of this approach requires an automated integration of design and analysis procedures. Guidelines for proper finite element modelling of slab systems are first presented along with simple post-processing algorithms to perform automatically the design or verifications from the analytical results. Numerical applications on simple slab systems subjected to uniform and concentrated loads are then used to illustrate the relative performance between finite element analyses and the equivalent frame method. Key words: microcomputer, reinforced concrete slab, finite element method, structural design.

Near Wall

Near-wall microenvironment of a building refers to parameters such as wind speed, temperature, relative humidity, solar radiation near the building’s façade, etc. The distribution of these parameters on the building façade shows a certain variation based on changes in height. As a technology of passive heating and ventilation, the effectiveness of this application on heat collection wall is significantly affected by the near-wall microclimate, which is manifested by the differences, and rules of the thermal process of the components present at different elevations. To explore the feasibility and specificity of this application of heat collection wall in high-rise buildings, this study uses three typical high-rise buildings from Zhengzhou, China, as research buildings. Periodic measurements of the near-wall microclimate during winter and summer were carried out, and the changing rules of vertical and horizontal microclimate were discussed in detail. Later, by combining these measured data with numerical method, thermal process and performance of heat collection wall based on increasing altitude were quantitatively analyzed through numerical calculations, and the optimum scheme for heat collection wall components was summarized to provide a theoretical basis for the structural design of heat-collecting wall in high-rise buildings.

High Rise

With the continuous development and progress of society, the structure of high-rise buildings has been paid more and more attention by the engineering community. However, the existing high- rise structure design methods often have a lot of redundancy and have a lot of room for optimization. Most of the existing seismic design methods of high-rise structures are based on engineering experience and manual iterative methods, so that the efficiency of design can not meet the needs of the society. if the method of design automation is adopted, the workload of designers can be greatly reduced and the efficiency of structural design can be improved. Based on the digital modeling theory, this paper proposes a MAD automatic design algorithm, in which the designer provides the initial design of the structure, and the algorithm carries out the modeling, analysis, optimization and design of each stage of the structure, and finally obtains the optimal structure. The structural design module of this algorithm starts from the component level, when the component constraint design meets the limit requirements of the specification, it enters and completes the component constraint design and the global constraint design of the structure in turn. In this paper, taking a ten-story braced steel frame high-rise structure as an example, the optimal design is carried out, and its seismic performance is analyzed. the results show that the MAD automatic design algorithm can distribute the materials to each part reasonably, which can significantly improve the seismic performance of the structure and realize the effective seismic design.

High Chance

The design of skyscrapers involves lot of aspects such as the building must withstand heavy dead loads, should have safety measures against fire, floors must be easily accessible, and should have resistant against wind and seismic loads that can be detrimental to the safety of the skyscraper. Pile foundations are usually adopted for high rise buildings and when it is combined with raft slab they ensure that the problems of differential settlement are taken care of. In this paper the scenario of designing a skyscraper in seismic zone that is prone to earthquakes and the ground condition is such that it is located in vicinity of sea. Andaman and Nicobar isle is one similar place it falls under Zone V as per Indian Standards, hence prone to seismic activity and since it is surrounded by Bay of Bengal and Andaman sea, when seismic activity occurs there is a high chance of soil liquefaction to occur hence proper structural designs should be embraced.

Building Information

In this works 3D modeling, design and safety management of high rise building using building information modeling (BIM) technology is carried out.. Initially a AutoCAD plan with all its salient features is developed following byelaws of high rise building. Then the 3D modeling and rendering of high rise building is done in the Revit architecture of the 2D plan which is imported from the AutoCAD. The analysis and design of high rise building is carried out using ETabs software. Apart from the structural design Mechanical, Electrical and Plumbing (MEP) services design is carried out using BIM technology . The layout of fire safety system is specified efficiently with use of BIM in co-ordination with MEP services. The application of BIM based design process resulted in considerable time reduction in compression with traditional design process and the holistic design of the high rise building is carried out with the compatibility of different softwares.

In Transit

In order to use urban space effectively in Transit-Oriented Development (TOD), over-track buildings (built over railways), are becoming increasingly popular in Japan. From a construction and structural design point of view, the basement structure just beneath railways generally cannot be built while railway operations continue (interruption to operations is not permitted, In general).This paper presents the structural design of a mid-story isolated high-rise building constructed over railways in Ikebukuro, Tokyo. The paper shows, not only the philosophy of the system, but also the structural design, full-scale experiments, and evaluation of the performance in each structural element. The authors believe that such a structural design will be one of the effective solutions to the over-track building.
