**help i hav no idea how to work out the design load!**

## Homework Statement

A typical floor layout of a reinforced concrete office building is shown in Figure 5. The

reinforced concrete floor supports a permanent dead load G (ceiling services, floor finish and

partitions, but not self-weight) of I.OkPa and superimposed live load Q of 3.0kPa. The slab

thickness is I60mm and beams are 450mm deep and 300mm wide as shown in Section A-A

in Figure 5. The concrete characteristic compressive strength (f"c) is 32MPa and steel yield

strength (fsy) is 500 MPa. For the beams, the cover to the ligatures is 30mm.

## Homework Equations

(a) Determine the design load in kN/m based on the given loads and using an appropriate

load combination;

(b) Find the maximum design negative and positive moments along the beam using the

simplified method;

(c) Find the maximum shear forces along the beam;

(d) Design the flexural reinforcement required to satisfy the maximum negative and positive

design moments as calculated in part (b). Use N20 bars for the flexural reinforcement

(curtailment details of reinforcement is not required);

(e) Design the shear reinforcement to resist the maximum design shear force. Use NI2 for

shear ligatures.

## The Attempt at a Solution

i atempted it and hav looked at the solution but can't seem to work out my dead loads

heres the solution for part A

w*= 1.2G+1.5Q = 1.2(11.5 _2.1+3) + 1.5 *9 = 33.4 kNm
