   Abstract The principal objective of this project is to analyze, design and make building estimation of a multistoried building [G + 4] using STAAD Pro and MS EXCEL. The design methods used in STAAD-Pro analysis are Limit State Design conforming to Indian Standard Code of Practice. The structure was subjected to self-weight, dead load, live load and seismic loads under the load case details of STAAD Pro. The supports at the base of the structure were also specified as fixed. Then STAAD Pro was used to analyze the structure and design the members. In the postprocessing mode, after completion of the design, we can work on the structure and study the bending moment and shear force values with the generated diagrams. The design of the building is dependent upon the minimum requirements as prescribed in the Indian Standard Codes. Strict conformity to loading standards recommended in this code, it is hoped, will ensure the structural safety of the buildings which are being designed.

   I.INTRODUCTION

   The construction in this 21st century is becoming challenging day by day as in order to achieve more economy and efficiency. As in order to bring down these challenges and save time, computer-based software programs are used by engineers. In this project after having the theoretical knowledge about the analysis and design of building we have attempted to G+4 residential building using this software also estimation using MS Excel. Our project involves most popular softwares like Auto Cad, Staad Pro and MS Excel.

   1. Auto Cad: – One of the main benefits of AutoCAD is that it allows you to draw to scale and accurately, Easy Layout and Viewing, we can make changes easily and reduce risk of error, identify design problems, calculate material quantities for production store and transfer data safely save time and money.

      The ground and all floors plan were drawn using Auto Cad. Also, column, footing plan was constructed in it

   2. The STAAD Pro CONNECT Edition: – It is used to generate the model, which can then be analysed using the STAAD engine. Design, including design for durability, construction and use in service should be considered as a whole. The design of the building is dependent upon the minimum requirements as prescribed in the Indian Standard Codes.

   3. MS Excel: – It helps in maintaining bills, making graphs, S scheduling things for a project, calculating sizes of beams and columns, etc for a civil engineer, in times of executing, quantity estimating, planning, contracts, budgeting, designing, quality controlling, quantity estimating etc. As stated, everyone uses Excel. The required calculations are one by MS Excel. You can store, replicate, modify the data; however, one might want. In our Project we have done Building Estimation and Costing and prepared quantity measurement and abstract sheet using MS Excel.

3. ANALYSIS AND DESING USING STAAD PRO:

1. LOAD CONSIDERATION

   (a). DEAD LOAD: –

   [IS 875(Part 1):1987 This is a Code of practice for design loads (other than earthquake) for buildings and structures Part 1

   (c). SEISMIC LOAD: –

   Dead loads Unit weights of building material and stored materials (second revision)]

   The dead load comprises of the weights of walls, partitions floor finishes, false ceilings, false floors and the other permanent constructions in the buildings.

   • Dead load calculation

   1. Self-weight= 1KN (Y axis).

   2. Member load (ML)= wall thickness X (Floor Height-Beam Depth) X unit weight on masonry.

      1. on External wall=5.875KN/m

      2. on Internal wall=3.675KN/m

      3. Parapet wall (1m Height) =1.25KN/m

   3. Plate Load= 2KN/m.

   (b). LIVE LOAD: –

   [IS 875(Part 2):1987 This is a Code of practice for design loads (other than earthquake) for buildings and structures: Part 2 Imposed loads (second revision)]

   Imposed load is produced by the intended use or occupancy of a building including the weight of movable partitions, distributed and concentrated loads, load due to impact and vibration and dust loads.IS 875 part 2 is taken as reference. The live load is taken as <=3KN/m i.e., 2KN and Live load for terrace =-1.5K

   Where, h = Height of building, in m. This excludes the basement storeys, where basement walls are connected with the ground floor deck or fitted between the building columns. But it includes the basement storeys, when they are not so connected. The approximate fundamental natural period of vibration (T,), in seconds, of all other buildings, including

   [IS 1893: Part 1: 2016 Criteria for Earthquake Resistant Design of Structures – Part 1: General Provisions and Buildings]

   1. Design Lateral Force

      The design lateral force shall first be computed for the building as a whole. This design lateral force shall then be distributed to the various floor levels. The overall design seismic force thus obtained at each floor level shall then be distributed to individual lateral load resisting elements depending on the floor diaphragm action.

   2. Design Seismic Base Shear

      The total design lateral force or design seismic base shear (Vb) along any principal direction shall be determined by the following expression:

      Vb = Ah W

      Where,

      Ah = horizontal acceleration spectrum W = seismic weight of all the floors

   3. Fundamental Natural Period

      The approximate fundamental natural period of vibration (T,), in seconds, of a momentresisting frame building without brick in the panels may be estimated by the empirical expression:

      Ta=0.075 h0.75 for RC frame building Ta=0.085 h0.75 for steel frame building

      moment-resisting frame buildings with brick lintel panels, may be estimated by the empirical Expression:

      T=.09H/D

      Where, h= Height of building=15.9m

      d= Base dimension of the building at the plinth level, in m,along the considered direction of the lateral force=20m,13m in X and Y direction respectively.

      (Ta)x=0.3199 sec and (Ta)z=0.3968

   4. Stiffness Reduction Factor for RC and Masonry Column= 75%, Beam=30%.

   5. Scale Factor= ZI/2R=0.0432

      Z= Zone Factor= 0.36 I= Impotent factor= 1.2

      R= Response reduce factor= 5

   6. Seismic Live Load= 25%LL=0.5KN
