- 3. 3 INTRODUCTION Petrochemical refineries are huge structure with different pipelines handling streams of oil and chemicals through the large chemical processing units. To keep this process constant, pipes must be stable against eccentric forces generated by its self-weight, thermal, seismic or wind actions and external means like, electrical, instrumental, telecommunication cable trays, auxiliary equipment like air cooler, pressure sustaining valves etc Therefore in this study, steel tonnage of structure is reduced for sustainability by implementing Innovative Bracing pattern at appropriate locations of pipe rack for the optimized design of sway and tonnage of structure. It is observed that lateral movement decreases up to 80% due to the incorporation of the bracing system. …(Ref. Nayanmoni Chetia, 2016)

- 5. 5 OBJECTIVES To investigate the suitable type of bracing in industrial pipe rack steel structure. To investigate the accurate location of bracing in structure. Compare the different types of bracings V, A, X, K, Diagonal as per their benefits and drawbacks. To study the different loads and their behaviour on structure. To reduce the effect of horizontal loads on structure. To reduce the cost of structure by reducing the tonnage of structure.
- 6. 6 Being a very expensive and heavy structure because of lots of heavy load, it has to be more stable and should be designed for lateral forces. To achieve that, the design required is also heavy. This heavy design can be reduced by implementation of bracing system. There are different types of bracing can be used for different structure appropriately. So it is essential to find out perfect type of bracing for industrial structure with its appropriate location.

Siddiqi, Rashid Hameed, “Comparison of Different Bracing Systems for Tall Buildings” concluded that, When a tall building is subjected to lateral or torsional deflections under the action of fluctuating wind loads, the resulting oscillatory movement can induce a wide range of responses in the building’s occupants from mild discomfort to acute nausea. As a result, lateral stiffness is a major consideration in the design of tall buildings. In this research study, five different types of bracing systems have been investigated for the use in tall building in order to provide lateral stiffness and finally the optimized design. When columns are braced along their minor axis of bending, provision of ‘A’ bracing results in minimum value of lateral displacement compared to other four types of bracing systems.

An investigation on bracing configuration effects on behavior of concentrically braced steel frames :- Author :- Peyman Shademan Heidari, Roohollah Ahmady Jazany Peyman Shademan Heidari, Roohollah Ahmady Jazany, “An investigation on bracing configuration effects on behavior of concentrically braced steel frames ” In this research paper the study aims at considering the effect of different bracing configuration on Six five-story three-bay braced frames with three different patterns experimentally evaluated. In this research paper bracing pattern were same but the position of bracing were different. 9
