Hello Everybodytoday I came with new CHALLENGE in Design of Steel Structure.Who can Solve accept this CHALLENGE ??Thanks a lot

QEAD Rev:0 3 ver 01 9th July 201 7 Template A 1 F/QAP/021/001 Aim To carryout structural analysis and design of a welded steel Plate Girder for a [G+2] Multistoried steel building as per Eurocode EC3 and the UK National Annex clauses . Learning Outcomes On completion of this course work, the student shall be able to: 1. Determine the critical loads and derived bending moments in the members of simple structures. 2. Ensure that structural behavior in practice corresponds to the assumptions of the design by appropriate detailing of the structure Task Assignment [Module based mini project]. - Sem B - Feb 2018 Design of a welded steel Plate Girder for a [G+2] Multi storied building in Oman Expected Task: It is required to provide structural design and detailing for a [G+2] Multistoried Commercial building in Oman. Welded steel plate girders supported at the ends on steel columns are provided at the basement floor for to have wide open space for parking purposes. RCC slabs are suppo rted on secondary beams which in turn are connected to plate girders and end reactions of secondary beams are transferred as axial loads on plate girder. The building has dimensions of A (Horizontal direction in m ) x B ( Vertical direction in m) It is required to carry out structural analysis and design of the plate girder as per EC3 and the UK National Annex clauses. Table 1 . Show the relevant data regarding the grade of structural steel, grade of concrete, overall depth of RCC slab, spacing of secondary beams, spacing of Plate Girders, Permanent action(Dead load) due to floor finishes, Varying Action ( imposed loads ), and other details to be adopted in the design [These data’s are shown against your student number]. Any other data (standard dat a complying with EC3) not given may be suitably assume d and shall be clearly mentioned in the solution . Submission Requirement: Abstract: Write an abstract of the mini project work explaining the task carried out, various EC3 and UK NA clauses, justific ation for the assumptions made in the design, summary of the structural analysis and design results obtained and conclusions drawn. [Weightage: `10%] QEAD Rev:0 3 ver 01 9th July 201 7 Template A 2 F/QAP/021/001 Design of Plate Girder: Complete the following structural analysis and design tasks complying with the BS EN: 1993 -1 code specifications. Assume that the compression flange of the Plate Girder is fully restrained. The Plate Girder is supported on a heavy stiffened bracket at each end. i. Determine the loads, shears and moments on the plate girder due to loads including self -weight of the girder. ii. Determine dimensions of the plate girder and section classification iii. Assuming a non -rigid end post and ignoring the contribution of the flan ges, verify whether the end panel and intermediate panel of the web has sufficient shear buckling resistance. iv. Design the intermediate load bearing stiffener. v. Verify whether the bending moment resistance of flanges of Plate Girder Section is satisfactory. vi. Check for deflection due to live load only on the plate girder. [Weightage: 50%] Design of stiffeners: Load bearing stiffeners are to be placed below each concen trated load and intermediate web stiffeners are to be placed at 1000 mm c/c intervals along the plate girder. i. Design the load bearing stiffeners and intermediate stiffeners (consider no tension Field action in web) [Weightage:10 %] Connection of flange to web: i. Design a suitable welded connection to connect the flange and web. [Weightage:10 %] Draw relevant s tructural drawings to illustrate the following : i. Structural plan ii. Longitudinal Sectional Elevation and cross section of Plate Girder iii. Cross Section of Intermediate Stiffener and Load carrying stiffener [Weightage: 20%] [Total weightage: 100%] Important Note: (i) Do not design the RCC slab (ii) Do not design the secondary beams. But secondary beam sections can be assumed for drawing purpose.
