Abu Dhabi University College of Engineering Department of Architecture and Design Bachelor of Architecture Program Spring 2024 ARC460 Structures II Group Project Description Students will create two computer models representing the structure and loads of two different building structures. One represents a steel structure and the second is a cast-in-placed reinforced concrete slab-beam system. Apply suitable and realistic superimposed dead loads, live loads, and wind forces suitable to the Emirate of Abu Dhabi. Conduct analysis and design of structural elements using the computer program ETABS. The computer models for each of the two structures should represent a ground floor height of 4.5 m and all remaining floor heights are 3.5 m. Loads and Computer Model Dead load: Use the software to automate the calculation of the self-weight of the structural system. • Apply 25 cm cement modular units (CMU) to building exterior and selected interior beams. Slab thickness for the concrete building is 150 mm, and you can accept the default slab thickness for the steel building. • • The floor slabs are identical and must have at least 4 spans in each direction. Accept the default structural elements that are selected by the software for the steel building and use appropriate material properties accordingly. For the concrete building try beams with 250 mm width and 500 mm overall height, but increase the dimensions of they fail. Beams supporting concrete Exterior beams are L- beams while interior beams are T-beams. All concrete beams and slabs are made of the same concrete with 35 MPa compressive strength. All columns are rectangular with 50 MPa compressive strength. Initial column dimensions are 500 mm x 500 mm. Select suitable openings to accommodate staircase(s) and elevators, but no need to include reinforced concrete shear walls in either of the two buildings. • Use at least two openings for staircases and two for elevators. Live Load: 1 Discuss with the teaching a suitable live load that matches your building usage (residential, office, etc). Wind load: Identify suitable wind load parameters for Abu Dhabi Emirate including wind speed in m/s (mph). Choose a suitable exposure category (B, C, or D) for your building. This should be coordinate with the teaching assistant. Requirements and Deliverables A. Professional Report No part of the report can be written ks first person. Passive voice is expected for the report for example: ASCE 7-16 was used to determine dead and live load; flexural capacity of beams was calculated using ACI 318 ....., etc. Cover page including (term and academic year, course code and title, project title, group members names and IDs) Group Members Contribution. This page describes in detail the contribution of each group member. While few tasks are common, each member must demonstrate clear contribution to the project in order to receive credit. Each group member must contribute to the report writing and editing. By uploading the reports to Blackboard, each member is acknowledging that the report is free from plagiarism. • Table of Contents • List of Figures • Notes: 1. All figures that appear in the report must be numbered and must have caption: e.g. Figure 3.4: Bending Moment Diagram for Controlling Load Combination List of Tables (if any) Notes: 1. All tables that appear in the report must be number and must have caption: e.g Table 2.4: Wind Load Parameters (ASCE 7, 2016) Introduction One page description of the project and its objectives. Theoretical Background Theoretical background with CAD drawn figures covering topics related to steel and concrete design and related codes. Separate the remaining part of the report into two parts A for steel building, and B for concrete building. • Loads and Analysis Results Description of external design loads and load combinations, followed by discussion of the structural response for the controlling load combinations. Create two models, one where all beams are modelled rectangular, and another where the beams are modelled as flanged. Based on selected beams and selected columns, 2 which model (if any) produces higher values (shear forces, bending moments, etc.) and by how much? For all design sections of the report, you must indicate the following information before you showing the calculation: 1) the controlling load combination(s) for the moment/shear force/load that you are designing for, 2) screen shot from the software showing which beam/column/footing your designing calculation pertains to. This information will be used for validating your design calculations. • • • Concrete Building: Design of selected interior T-Beams and Exterior L-Beams Design calculations and cross-section details of two spans of selected beams in one particular floor, preferably near the middle stories of the building. One span is interior and second is exterior, but in the same frame. This must cover design of longitudinal reinforcement, shear reinforcement, and checking of development length requirements. Concrete Building: Design of selected column Design calculations and cross-section details of a column in the ground floor. Show your calculations details and quality figures. Steel building: Show the design details, with the aid of the software, for a selected compression member (column). Steel building: Show the design calculations for bracing (tension member). Make all necessary assumptions. Summary. This must be one page long summarizing all activities. References Mandatory Instructions for Report 1. References should include as a minimum, the class textbook, ACI 318-14M, ASCE 7-2016, and two books from our library. List of references should not include more than two websites. 2. All references must be cited within the report. 3. All of the report must be typed using in MS Word and all figures must clear and readable (report that is not typed will be graded to a maximum of 50% of the total grade). Use the equation editor in MS Word. 4. The report cannot include the step-by-step presentation that illustrates how you created the computer model. The step-by-step presentation is a separate document. B. Step-by-step PowerPoint Presentation Create a step-by-step presentation showing the steps followed to create each of the two computer models. Each slide is a screen shot showing the step with short annotation (two-line description of the model). Deliverables: 1. Project report (Word file), 2) Step-by-step PowerPoint presentation, 3) Two ETABS files for each model (.edb and .e2k). 3/n• Concrete: • Concrete Building Beams: ° Design of selected interior T-Beams and Exterior L-Beams Design calculations and cross-section details of two spans of selected beams in one particular floor, preferably near the middle stories of the building.
