Academic year 2024/25 3/22 University of East London School of Architecture, Computing and Engineering EG7006: Advanced Structural Analysis Module Leader: Dr Ali A. Abbas MSc/PGDip in Civil Engineering MSc/PGDip in Structural Engineering COURSEWORK Academic year 2024/25 4/22 FORMATIVE ASSIGNMENT 1: Structural Analysis of building structures GROUP 1: Suspended Multi-storey building As part of the regeneration plans for East London and to address housing shortage, a reinforced-concrete building is to be constructed above an existing canal and as such it will have to stand on two side cores to allow a clear path for the canal beneath. The building comprises parallel frames and has F floors. The spacing between frames is S. Each frame has N bays and the span of each bay is L. The height between floors is H. Each side core is a concrete wall with a rectangular section of width W and breadth T. The interior columns (ties) at the centre of the frame are made of pre-stressed concrete with a square section of width C. The beams have a section with breadth b and depth d and a length L. Parallel steel trusses are placed at the top of the building (directly on top of the frames) and each has a variable depth from D1 (at mid-span) to D2 (at the ends). It has M equal segments along the span. The truss elements have a cross-section profile B. Carry out background review on suspended buildings and their uses. Explain the key structural differences between suspended and non-suspended buildings. Create a model of the structure using the structural analysis package provided. Carry out a mesh sensitivity analysis for each case. Obtain the deformed shapes and the internal forces diagrams (i.e. shear forces, bending moments, compressive and tensile axial forces on all beams and columns) when the building is subjected to a uniformly distributed quasi-permanent action q acting on all floors. Assume the beams are rigidly connected to the core walls and continuous over the interior columns. Explain the load path. Obtain the deformed shapes and the internal forces diagrams due to the load q if the beams are pinned to the core walls and the interior columns. Explain the load path. Repeat the steps above when additional central columns are located in the ground floor (directly beneath the ties) and the truss removed. Explain the load path. Compare the results obtained from all the cases above and write a set of essential conclusions about this work.

The building has N bays and M floors. The spacing between frames is X and the span length of the bays is Y. The concrete floors have a thickness T. The height between floors is H. The floors effective width for the floors can be determined by the maximum of 10% span length and 5 times the slab thickness. The beams are made up with profiles T1. The columns are made up by profiles T2 (between 1st and 15 th floor), T3 (between 15 th and 30 th floor), and T4 (above the 30 th floor). Create a model using the structural analysis package provided. Carry out a mesh sensitivity analysis for each case. Obtain the horizontal displacements in all of the floors when a horizontal uniformly distributed wind load w is acting over the entire building. Choose a suitable bracing system in the first bay in order to reduce the horizontal deflection at the top of the building obtained in the previous section by n%. Repeat the steps above if the slab is subjected to a vertical live load q acting on all floors in addition to gravity loads. Determine the results initially for the vertical loads only and then for the combined vertical and horizontal loads. Repeat the steps above if the slab is subjected to a vertical live load q acting on alternate floors (even numbered ones) in addition to gravity loads. Determine the results initially for the vertical loads only and then for the combined vertical and horizontal loads. Compare the results of the above analyses and write a set of essential conclusions about this work. N = 4 + Nstudent M = 40 X = 5
