Design of Reinforced Concrete Structure and One-way Slab and Beam

Logical approach to design of slabs, beams and columns

·Logical approach to design of slabs, beams and columns showing the efficiency of each member regarding bending, shear, compression and deflection, as appropriate;

·Practical application of judgement to ensure the reinforced concrete structure is economical to construction;

·Presentation of the portfolio with technical drawings is an important factor in convincing the client of the designers’ professionalism;

·Under H&S legislation the designer is responsible for the safe construction as far as the structure should be buildable, hence the detail of the method statement should be sufficient to show the H&S of the site operatives have been taken into consideration.

·Produce at least a drawing for plan view and a draw for elevation view,

·Illustrate the structural grids – positions of beams and columns and estimate their dimensions,

·Specify the directions of roof and floors spans and estimate their thicknesses,

·Indicate the locations of the atrium, lifts and stairs.

·Analyse the slab linked to the design and indicate its location in your drawings,

·Define the grade of concrete to be used for the slab and determine the slab thickness for satisfying the fire requirements,

·Determine the design load on the slab to UK NA to EN 1991-1-1 (Category B1),

·Design the suitable tension reinforcement with respect to bending,

·Check the suitability of the proposed slab with respect to shear,

·Check the suitability of the proposed slab with respect to cracking,

·Check the suitability of the proposed slab with respect to serviceability deflection requirement,

·Check other requirements for the reinforcement and detail it in the slab (e.g. secondary reinforcement, bar shape, minimum/maximum areas, bar spacing, etc.),

·Discuss the buildability and H/S issues during the construction of the slabs,

·Provide with appropriate technical drawings with steel details.

·Analyse the beam linked to the design and indicate its location,

·Define the grade of concrete to be used for the beam and determine the beam dimensions for satisfying the fire requirements,

·Determine the design load on the beam,

·Design the suitable reinforcement with respect to bending,

·Design the suitable reinforcement for the beam with respect to shear,

·Check the suitability of the proposed beam with respect to cracking,

·Check the suitability of the proposed beam with respect to serviceability deflection requirement,

·Check other requirements for the reinforcement and detail it in the beam (e.g. bar shape, bar curtailment, minimum/maximum areas, bar spacing, etc.),

·Discuss the buildability and H/S issues during construction of the beams,

·Provide with appropriate technical drawings with steel details.

·Analyse the column linked to the design and indicate its location,

·Define the grade of concrete to be used for the column and determine the column dimensions for satisfying the fire requirements,

·Determine the design load on the column,

·Check if the column is short otherwise re-design the column,

·Design the suitable longitudinal reinforcement with respect to combined axial load and nominal bending,

·Design the suitable reinforcement for the column with respect to shear,

·Check other requirements for the reinforcement and detail the reinforcement in the column (e.g. bar shape, minimum/maximum steel areas, bar spacing, etc.),

·Discuss the buildability and H/S issues during the construction of the columns,

·Provide with appropriate technical drawings with steel reinforcement details.

For Graduate Apprentice (GA) students only, alternatively, you can select a civil engineering work from your projects at work, e.g. a RC frame hotel/office/school building, a RC bridge for traffics or pedestrians, an aqueduct for canal, etc., and try to design a simply supported slab, a simply supported beam and a short column of reinforced concrete for that civil engineering work based on the knowledge learned from this module so far.
