Provide the strength calculations for the design of the following simply-support

Question

Provide the strength calculations for the design of the following simply-supported composite beam in accordance with Australian guidelines:

Beam length = 12 m

Slab thickness = 130 mm

Concrete strength = 35 MPa

Beam spacing = 2.4 m

Live load = 3 kPa

Superimposed dead load = 1 kPa

Include and/or specify other assumptions as necessary. Beam designed with a degree of shear connection = 0.5

This should include only the main steps related to the composite design. It must include at least the calculation of moment capacities with different levels of shear connection.

Solution:

"I am done with the design but not sure about the part given below:"

Discussion of changing the design parameters (e.g. concrete strength, beam spacing, beam span, loading etc) on the floor beam design. The discussion should include critical considerations (and not just plots without comments)

Explanation / Answer

changing the design parameters like concrete strength, beam spacing, loading will chage our full design. for eg. if we change the strength of the concrete then may be it will require more reinforcement than of now. If we change the load such that load increases then we have to increase the strength if beams either by increasing depth or change the support conditions. If beam span is increased then we have to modify our design by giving supports.
