ABSTRACT The paper presents the plan, examine and outline of a vertical general office

building of G+4storey and explore its execution under different loading conditions. The fundamental objective is to evaluate current Indian Standard design practice and to give outline rules utilizing ETABS and this Software used to analyze and design particularly the buildings. Because of the facilities gave in this product at the modeling stage, the structures can be modeled according to the arrangement of the members from the project in Practical, and this software considers of beams, columns as line members; slabs, staircases, walls are as area members. Taking the horizontal loading impacts of Wind and Seismic forces; in the design of this plan, we bring dynamic loading alongside the Static loading and Live loads according to IS Code.

1. INTRODUCTION This paper will help to build within the constrained range fulfilling each of each need of the general population. It is additionally planned in a manner that it would be economical. A Structural Architect must be acquainted with arranging, examination and outline of such structures against different loading. Today, the way toward planning of structures is overwhelmed by PCs. Programming devices utilized as a part of configuration stage can robotize redundant counts and drawing errands. Subsequently it was proposed to pick a commercial building to examine and configuration concurring to demands.

2. METHODOLOGY

The proposed four storied commercial building comprise of area of floor is 31.6 m2 with 40.15 m2 plot measure. A building ought to be wanted to make it agreeable, conservative and to meet every one of the prerequisites of the people. The shopping center to be examined and

composed according to BIS details is arranged and drawn utilizing PC helped drafting programming program, AutoCAD, to make exact drawings utilized as a part of development and assembling.

2.1. About the Commercial Building The Rough Built–Up Region of Business Building i.e. an Office Building is 71.75 sq. m

In basement the entire region is assigned for parking of 31.6 m2 and 40.15m2.

In first floor entire area is 34.05Sq.m.

In second floor entire area is 34.05Sq.m.

In third floor entire area is 34.05Sq.m. The purpose of the building is commercial which is in the shape of rectangular having

G+4 stories with a depth of foundation of 1.5m by using brick wall.

2.2. General conditions for the proposed area of construction The area of construction is Hyderabad. The project is taken in rainy season in the month of

August.

The approximate temperature during construction is 30degree centigrade, having humidity up to 25-27%. Soil condition during the time of construction is medium stiff.

Hyderabad lies in the Zone-2 having Zone factor 0.10

2.4. Load Criteria The entire design is done by the code arrangement IS: 456:2000. The load that following up on the structure is taken from the code arrangement IS: 875 part 1,

2, 3. Self – weight (1) Slab load for one meter width = (1x0.18x25) +1 =4.75KN/m^2 Floor finishing =1.6 Wall load

External wall= (3.05x0.23x18) = 12.627 KN/m^2 Internal wall = (3.05x0.115x18) = 6.3135 KN/m^2 Parapet wall = (1.5x0.115x18) = 2.484 KN/m^2

3. DESIGNING The entire limit state that are relevant are considered in the design to ensure serviceability the structure in general shall be designed on the basis of the most critical state and shall also be checked for other limit state

The Indian Standard (IS) code used for the design Minimum design loads for Buildings other than seismic loads IS 875 (Part 1): 1987 Dead loads IS 875 (Part 2): 1987 Imposed loads IS 875 (Part 3): 1987 Wind loads IS 875 (Part 5): 1987 Special loads and load combinations IS 1893: 2002 Criteria for earthquake resistance design of structure

3.2. Design Criteria Suitable grade of concrete selected for construction is M35i.e. fck =35 N/mm^2 Grade of steel used is Fe 415 i.e. f y= 415 Density of concrete taken is 25 kN/m3 Calculated density of concrete for5000 N/mm^2 is 2958000 N/mm^2 Density of steel is taken as 78.5 kN/m3 Modulus of elasticity of steel is 2 x 105 N/mm^2 size if the beam is 400mmX600 mm size of the column is 750mmX750 mm thickness of the slab is 175mm each storey height is 3m number of stories is 4 support conditions are taken as fixed

4. ETABS DESCRIPTION

The project deals with the design and analysis of G+4 building in ETABS. A step-by-step procedure for designing and analysis of structure using ETABS is explained

through a simple example. Subsequently the usage of gravity loads analysis on structure is explained. The loads are applied on the exterior and interior beams based on the type of wall. The typical floor plan from the AutoCAD is taken and designed it in ETABS. Then the structure is analyzed to check the design. By using these steps we can design the

required G+4 building. 5. RESULTS AND DISCUSSION

Fig-3 Framing and 3D View of the building shows the building consists of four storeys with beams columns and slab and loads assigned as per Indian Standards



Figure 4 diaphragm

Define response spectrum functions and cases and from default design combinations design load combinations and in mass source, change the dead load as 1 and live load as 0.5. Then assign shell area in which diaphragm will be appeared.

After the results and analysis the design of the structure is obtained by checking the structure and change

The units into N-mm in order to view the values clearly.
