Project Description

Design the 1st floor slabs of a 3-storey office building in Melbourne using a flat plate floor system with no beams. Utilize SLB Inducta software for analysis and design, considering loads, slab thickness, reinforcement, deflection, and punching shear.

Details

• Live load: 2 kPa for which ys = 0.7 and y1 = 0.4
• Number of spans in x and y direction: 4 in each direction
• Span length: “last digit” of student number if last digit is equal to or greater than 5, “last digit + 5.5m” if last digit is less than 5. As example if student number is 19850, 0 is the last digit and is less than 5. So, span length is 0+5.5m.
• Floor height 3 m
• Concrete strength, fc ’= 40 MPa
• Use N bar only with 500 MPa
• Consider 30 mm concrete cover over the reinforcements.
• Consider 500×500 mm for the columns’ sizes
• Limit the total slab deflection to ∆ Lo/= 1/25
• EC = 30100 MPa
• Yrc = 25 kN/m⊃3;
• ecs = as per the AS3600-2018 requirements

1. Model in SLB Inducta:

Model the slabs of the 1st floor in software. Input the relevant structural data (slab thickness, reinforcement details, concrete specifications), load values (consider loads given above) and load combinations into the software.

2. Structural Analysis and Reinforcement Design:

Mesh the model and run the software to analyze the slabs’ behavior under the specified loads/combinations and obtain the design results. Determine the necessary amount of bending reinforcement (steel bars) in x- and y- directions to provide tensile strength and resist structural stresses.

3. Short- and Long-Term Deflection Checks:

Check the deflections of the slabs (one corner, middle and one side slabs) to ensure they meet serviceability and safety requirements.

4. Punching Shear Checks:

Check the punching shear of the slabs at the top of all columns.
