Analysis and Design Of Cricket Stadium

Abstract

The stadium structure is a memorable landmark of many architectural structures. A modern sports stadium is a place or venue for sports, concerts or other events, consisting of a field surrounded by a structure designed to allow spectators to stand or sit to view the event. Stadium should be a national flagship and designed for international standards. Sports stadium should be designed to satisfy all criteria regarding economy, safety, serviceability and esthetics. Stadium consists of mainly roof and main frame. From design perspective, the roof is one of the stadium’s most challenging features as it has wide material options , geometric options and structural system options. Steel is one of the materials which is commonly used for large span structures like roof systems. There are many roofs structural systems like cantilever truss, space truss, cable roof which can be possible to cover the structure. Main frame is of either R.C.C. or steel. Main frame consists of seating tiers for spectators and it supports the roof system. For connections, generally welding is used. For the present study Rajkot Cricket stadium is taken. The ground seating tier is already exists. To increase capacity of stadium from 12,000 to 30,000, additional three seating tiers and roof system needs to be designed. The objective of the study includes analysis, design and detailing of roof and R.C.C. frame of stadium. This study is carried out with help of “STAAD-Pro 2006” to obtain accurate analytical results. Excel spread sheets are used for design of different members. For roof, 21m long span cantilever roof is designed. Main frame is of R.C.C. consisting of three seating tiers, hotel rooms and gallery. An attempt is made to design a 21m cantilever roof truss as per IS: 800(1984) and IS: 800 (2007). An alternate system for roof with 4RHS sections, 3RHS sections and pipe sections and channel sections is also considered and these alternatives are then compared in terms of their weight aspects. The main frame including slab, columns, beams, supporting system is analyzed using STAAD.Pro and designed using MS Excel spread sheets. The study also IV covers quantity calculations, rate analysis and costing of structural system designed. The content of major project divided into various chapters. Chapter 1 includes introduction objective of study, and scope of work and problem definition. Chapter 2 covers literature review to find out different design approaches, innovative architectural ideas and guidelines for the study. Chapter 3 comprises of analysis, design and detailing of roof structure. Designing is done using rectangular hollow section (RHS) using IS: 800(1984). Detailed drawing of members designed is included in this chapter. Chapter 4 includes analysis, design and detailing of R.C.C. frame. 3D model prepared in STAAD.Pro is used for analysis. This chapter also covers design steps and detailing of roof, slab, beam and column. The same roof is also designed using IS: 800(2007) provisions which is included in chapter 5. Alternate systems for roof are included in chapter 6. Chapter 7 includes quantity calculation and total cost of structure of stadium. Finally chapter 8 includes summary of project and future line of action for this major project.
