Calculation

Wind Load (WL) = WP x m= .007 x 123.5= 0.86 kg/cm negative pressure

Berat MaterialArea of Mullion = 6.62 cm2 Luas penampang mullion

Area of Transome = 3.95 cm2 Luas penampang transome

Kaca = m x (ht + hb) x tg x gb= 123.5 x (352.5 + 40) x 1.4 x 0.0025= 169.66 kg

Mullion = 2 x (h x Am) x 2.78T/m3

= 2. x (352.5 + 40) x 6.62 x 2.78T/m3= 14 kg

Transome = 4 x m x At x 2.78T/m3

= 4. x 123.5 x 3.95 x 2.78T/m3= 5 kg

Berat total Material = Kaca + Mullion + TransomeSDL = 190 kg

Shear Load FactorBased on Inertia

Sm = Ix / (Ix + Ic)= 156.4 / (156.4 + 91.51)= 0.631

Sc = Ic / (Ix + Ic)= 91.5 / (156.4 + 91.51)= 0.369

Mmax = 11057.00 kg.cmDefl = 0.77 cm

Momen mullion = Mmax x SmM max = 11057. x .63

= 6975.08 kg.cm

Momen cover mullion = Mmax x CmCV max= 11057. x .37

= 4081.92 kg.cm

Check Mullion CapacityKapasitas Momen = Pb x Zx

Mullion (Mr) = 1100 x 18.48= 20331.80 kg.cm

Kapasitas Momen = Pb x ZxCover Mullion (CVr) = 1100 x 10.47

= 11517.28 kg.cm

Ratio Mullion = M max / Mr

= 6975.08 x 20331.8= 0.34 < 1 OK!

Cover Mullion = CV max / CVr= 4081.92 / 11517.28= 0.35 < 1 OK!

Distance vertical max of Screwdv = Pa / WL

= 64.77 / 0.8645= 74.93 cm

Calculation of Transome Typical Effect Wind Load & Dead Load

Zx = 5.23 cm3

Zy = 3.14 cm3

Ix = 18.34 cm4

Iy = 8.55 cm4

Calculation

Wind Load (WLA) = Wp x (L / 2) x 2= .007 x (123.5 / 2) x 2= 0.86 kg/cm

Dead Load (DL) = L x Tt x tg x dg / 2= 123.5 x 200 x 0.8 x 0.0025 / 2= 24.7 kg
