Analysis and Desin of Multi purpose Auditorium

  1. 1. Analysis and Design of a Multi-Purpose Auditorium using STAAD.Pro v8i BY GROUP : 13 V. KRISHNA MADHUKAR 12241A01B6 V. VISHNU SAI 12241A01B7 R. SAI DEEPAK VARMA 12241A01A6 J. RAJENDER 13245A0122 J .RAJKUMAR 12241A0182 UNDER THE GUIDANCE OF DR. C. LAVANYA DEPARTMENT OF CIVIL ENGINEERING IET
  2. 2. ABSTRACT An Auditorium is a room built to enable the audience to hear and watch various activities such as performing arts, conducting cultural events, professing lectures, and carrying out various presentations and seminars. As it could be used for all the occasions stated above it is called as Multi-purpose Auditorium. This project deals with the “ANALYSIS & DESIGN OF AN MULTI-PURPOSE AUDITORIUM USING STAAD.Pro v8i”. The design will be in confirmation with IS 456:2000 and SP16 for plain and reinforced concrete, IS:875-1987 Part 1,2,3 for Dead load, Live load and Wind load calculations,IS:1893-2002 for Seismic loads and IS 2526:1963 for acoustic design. The plinth area of the proposed Auditorium is 1900 Sq m with a Seating capacity of 750 Nos, height of the Auditorium will be at two levels +4.35m and +7.325m. M30 Grade of concrete and Fe- 500 steel will be used for all VRCC (Vibro-Roller compacted concrete) works. Bored cast-in-situ end bearing piles with M30 grade of concrete will be used for foundation works.
  3. 3. PLAN & DETAILS  Plinth area of the proposed Auditorium is 1900 Sq m  Seating capacity of 750 Nos  height of the Auditorium 7.325m  Bored cast-in-situ end bearing piles
  4. 4. Analysis The procedure followed in analyzing the auditorium is: 1. Generating the STAAD.Pro model 2. Assigning assumed cross sections 3. Assigning different types of loads and defining load combinations 4. Run the analysis 5. Verify STAAD output

  21. 21. Terminology Auditorium Foyer Lounge Proscenium Rear wall Balcony parapet Raking of Seats Reverberation Echo
  22. 22. Acoustic Requirements a) correct reverberation time, b) absence of echo, c) correct loudness level at all parts of the hall, d) low background noise,
  23. 23. General Principles of Acoustic design 1) Site selection Depending on ambient noise level Background noise should not be more than 40-45 dB 2) Size and Shape ◦ in relation to the number of audience required to be seated. ◦ Avg height – 6 to 7.5 m, Fan shape is considered best, sidewalls shall not be more than 100 degrees, Farthest seat shall not be more than 23 m with the curtain line 3) Stage Depends upon the type of Performance the hall is to cater for,
  24. 24. 4) Roof and ceiling False ceiling, Sound proof material Rear portion of ceiling is treated with sound absorbing material 5) Floor Successive seats have to be raised over preceding ones, so that the listener head is about 12 cm above the path of sound, which would pass over the head of the front person. Angle of elevation of the inclined floor in auditorium should not exceed 8degrees 20% of the seating area should be allocated for lobby, Foyer 6) Seats The angle subtended with the horizontal at the front most observer Should not exceed 30 degrees Distance between the stage and front row should be 3.6m – 4.5m Width of seat – 45- 56 cm Distance between seats back to back – 85 - 106cm 7) Reverberation time : Reverberation time is defined as the time it takes for an impulse of sound in a room to decay 60 dB, or one millionth of the original level. This value is affected by most everything in the room, including room volume, absorption of room materials, diffusion from surfaces, and room temperature and pressure
  25. 25. 8) Distribution of Acoustic Material Those areas which cause objectionable sound reflection and need to be treated with sound absorbents should be earmarked for treatment with sound absorbing material. These areas are (a) the rear wall, (b) the balcony parapet, (c)any areas which may reflect sound back to the stage, (d) concave areas 9) Sound Absorbing Materials In an average hall, most of the absorption is provided by the audience. It is therefore, becomes desirable to introduce special absorbers(such as wooden panelling) on ceilings and walls which will provide the requisite amount of absorption so as to achieve optimum reverberation-time.
  26. 26. ADDITIONAL SCOPE  Carrying estimation and costing of the project  Scheduling of the project by brainstorming various activities and time required for each activities  Managing construction phase using various project management tools like MS Project and Primavera.
  27. 27. Conclusion This project concerns the feasibility of construction of an auditorium with good acoustic properties. It involves the application of earlier coursework to carry out the analysis and design of components of structure. It was analysed using STAAD.Pro using generic loading, and AUTOCAD for drawing and detailing the c/s and l/s of structural members. The construction of auditorium presents a solution for many cultural programmes being held.
