Brief Estimating the Loads in Columns

Span of Planks = m Corbel size = mm

Span of beams = m Eccentricity = mm

Span of edge beams = m Column size = mm

1.0 ) Internal Column

(1.1) Maximum Axial Load P = kN

Location: Ground Storey, G/5 M = kNm

Loading: All floors fully loaded

Axial Load, P = 9.410.85(13.6+13.6+13.6+13.75+11.35)

= kN kN

(1.2) Unbalanced Moment

Location: Ground Storey, G/5 P = kN

Loading: All floors fully loaded except first floor. 1st floor loaded only on one side. M = kNm

Axial Load, P = 9.410.85(13.6+13.6+13.75+11.35) + 13.610.859.4/2 + 7.210.859.4/2

= kN kN

Moment, M = (13.6 - 7.2) 0.5 (10.859.4/2) = kNm

2.0 ) Edge Column(2.1) Maximum Axial Load + Bending Moment

Location: Ground storey I/4

Loading: All spans loaded P = kN

Axial Load, P = 9.44.725/2 (13.6+13.6+13.6+13.75+11.35) M = kNm

= kN kN

Moment, M = 9.44.725/2 13.6 0. = kNm kN

(2.2) Minimum Axial Load + Bending Moment

Location: Future roof level I/4

Loading: All spans loaded P = kN

Axial Load, P = 9.44.725/2 11.35 M = kNm

= kN kN

Moment, M = P e = 2750.5 = kNm kN
