Abstract : Civil engineering is a broad area in which buildings are planned and designed to meet specific needs. As we can see that many developments and changes happening in the sector of construction and everyday new commercial and residential building projects are initiated. As a result, thorough planning is required before beginning construction so that the work may be completed in a cost-effective manner while still meeting the needs of the users. The ETABS is an engineering software that helps in modelling, designing and calculating loads while making a structure. It is a very useful software in civil engineering field and provide a vast method to ease out the work of engineers. It analysis the structure in terms of static and dynamic loading conditions. The structure is analyzed in terms of static and dynamic loads. Today, there is a large scope in this subject, which allows many people to work in the respective field.

Ernakulam is a fast-growing metropolitan area. With this increasing growth comes problems of popoulation density, overpopulation and lack of land availability. To overcome this problem the most effective solution found out was high rise buildings. There are different types loading that act on a high rise building like wind load, earthquake load, live load, dead load etc.

In this we are focusimg on wind load analysis on high rise buildings.

1. INTRODUCTION

   Civil engineering is a broad area in which buildings are planned and designed to meet specific needs. As we can see, there are numerous advances and changes taking place in the construction industry, and new commercial and residential building projects are being begun on a daily basis. As a result, thorough planning is required before beginning construction so that the work may be completed in a cost-effective manner while still meeting the needs of the users. The ETABS is an engineering software that helps in modelling, designing and calculating loads while making a structure. It is a very useful software in civil engineering field and provide a vast method to ease out the work of engineers. It analysis the structure in based on static and dynamic loads. Today there is a huge scope in this field and it gives the opportunity to many people to work in this respective field.

   Ernakulam is a fast-growing metropolitan area. With this increasing growth comes problems of population density, overpopulation and lack of land availability. To overcome this problem the most effective solution found out was high rise buildings. There are different types of loading that act on a high rise building like wind load, earthquake load, live load, dead load etc. In this, we are focusing on wind load analysis on tall rise buildings.

2. METHODOLOGY

   The major focus of civil engineering is structural design. The design of the basic components and members of a building, such as Slabs, Beams, Columns, and Footings, is the most fundamental in structural engineering.

   • Preparation of plan using AutoCAD

   • Importing to ETABS

   • Building modeling in ETABS

   • Member Design

   • Assigning load as pear IS provision

   • Analyze structure using tool

   • Drawings and detailing

   • Results and Discussions

   • Conclusion

     Proposed Building Details

     The proposed residential building is having each apartment of 3bhk having individual staircase and lift system

     that help for easy access to grounds

     Datas For Modeling Concrete grades = M40 Steel = FE600

     Load Details

     Considerations are made for dead load, live load, wind load, and seismic load. Due to the equipment and other embedded structures' selfweight, dead load is a major factor. The load may be taken into consideration based on the unit weight of each item, as stated in IS 875 (part I).

3. CONCLUSION

The structure is based on the E-TABS design, which provides acceptable serviceability, strength, and economic work. Working time is saved by using E- TABS software, and it also assists us in precisely developing structures. The structural components were designed both manually and using software. There is not much land available in urban areas so buildings are constructed in storys to utilize the vertical space. Rather than destroying forests and swamps to build houses, shopping centers and factories, they can be placed in a vertical tower to serving to preserve the environment. The displacements, story shears increases as the wind speed increases. The high rise stories are more effected by the wind forces and the wind influence increases if the height of the structure increases further. It is observed that the lateral force excited on the structure have shown increasing severity with increase in the wind speed.
