CIVE1177 – CONCRETE STRUCTURES 1 PROJECT BRIEF This project will introduce you to the aspects of the structural design process of a building made from reinforced concrete. You need to design a three-storey building, and the specifications of the building are as follows: SPECIFICATION Loading: Floor Finishes 1.0 kN/m2 Waterproofs (roof) 0.5 kN/m2 Ceiling and services 1.0 kN/m2 Partitions 0.5 kN/m2 Exterior Wall (along gridline 4 only) 4.0 kN/m (100 mm thick) Live Load 1.0 kN/m2 roof 3.0 kN/m2 internal levels Characteristic concrete strength ��� = 40 MPa Concrete cover thickness = 25 mm Aggregate size = 20 mm Ductility class N high yield reinforcement for both longitudinal steel and shear reinforcement. Yield strength ��� = ����� =500 MPa - Maximum bar length = 6 m - 10 mm < bar="" diameter="">< 40 mm slab thickness = 200 mm (the 3 span slab runs one-way over the beams that run along gridlines a, b, c, and d) beam width = 325 mm. the overall beam depth is 600 mm beams are located at 5.0 m centre-to-centre. the beams run along gridlines a, b, c and d (see figure 1) column section to be 325 x 325 mm square foundation design: permissible soil-bearing pressure = 200 kn/m2 the structure has a floor structure on level 1 and level 2, plus a roof structure, and the ground floor slab is not supported by the columns but rests on the ground soil. the frame is assumed to be braced against lateral load (i.e. do not need to consider lateral loads such as wind loads in this project) figure 1. typical floor plan dimensions figure 2. building frame elevation (at gridlines a, b, c, d) figure 3. typical interior floor level – elevation scope ofwork you will be required to complete the following tasks: 1. develop preliminary structural frame system and draw the framing plan for level 2. 2. estimate primary loads and determine load combinations for strength and serviceability limit states 3. model and analyse the rc frame structure at gridline b using spacegass for appropriate load combinations 4. design the rc structures: (1) the continuous one-way slab from gridline a to d, (2) the rc continuous beam at gridline b, (3) one rc column at grid b/2 including the pad footing 5. draw the rc sketch drawings of the above designed elements for feedback students can submit the preliminary results for tasks 1-3 for feedback. no mark is allocated to this partial submission and it is not compulsory. further opportunity for feedback will be given in project workshop, monday 12:30 to 1:30 pm (starting from week 2, students attend only if you have questions). you may also utilize discussion board on canvas for feedback. submission guideline and mark allocation submit through canvas, 5% penalty per day overdue. task max mark % preliminary structural design plan design information, i.e. objective of project, assumed loads, material specification, and references. identification of gravity load paths preliminary framing plan for level 2 10 load analysis of the rc frame at gridline b estimate primary loads (dl and ll) on the rc frame and its load combinations rc frame set-up in spacegass spacegass load analysis, i.e. obtain design actions (m*, v*, n*) and their diagrams (bending moment diagrams, shear force diagrams, axial force diagram and deflected shape), resulting from the critical load combinations for (1) serviceability limit state, and (2) ultimate limit state computer model check using hand calculations, i.e. check total loads at the bottom of a column by doing manual column load run down 30 load analysis of one-way slab (level 2 only) estimate the load and design actions for a 1 metre width design strip inside the building spanning over the beams using the simplified method in clause 6.10 of as3600 5 design of reinforced concrete members (level 2 only) the one-way reinforced concrete slab analysed above the reinforced concrete continuous beam along gridline b the reinforced concrete column at grid b/2 the reinforced concrete pad footing at grid b/2 40 final drawings and reinforcement detailing for the rc elements designed above the one-way slab
