Calculation for New Canopy of Sands
Drawing:
introduction
The site is in Macau S.A.R.
Type of terrain roughness
According to the macau《Regulamento de Seguran?a e Ac??es em Estruturas de Edifícios e Pontes》
This case is the first class of terrain roughness
Calculate
Explanation of the load for the canopy
The load include dead load, wind load, and live load
Total:
Sk+=1.35Gk+1.5wk+1.5Sk(or Qk)
Wind load design value
ccording to the macau《Regulamento de Seguran?a e Ac??es em Estruturas de Edifícios e Pontes》:
Wkh=2.59kpa
Live load design value
ccording to the macau《Regulamento de Seguran?a e Ac??es em Estruturas de Edifícios e Pontes》:
Q:live load of the canopy:5kN/m2
Dead load of the canopy
Gk: Uniformly dead load of the canopy = 2.5kPa;
∵Gk compare with others load, is not the main load:
∴G+ =1.2×Gk
=3kPa
Consider all loads
Sk+ =1.35Gk+1.5wk+1.5Sk(或Qk)
=1.35x3kpa+1.5x2.59kpa+1.5x5kpa
=15.44kpa
Load from upper curtain wall
W k = ?z ?s ?z Wo
=2.25×1.5×0.74×1.1×eq 0.7
=1.923KN/m2
W=1.4WK=2.692KN/m2
qEk=3.0×eq 0.08×0.6=0.144KN/m2
qE=1.3X0.144=0.188 KN /m2
W合=2.692+0.6×0.188=2.805 KN /m2
q1= W合×H/2=2.805×4.3/2=6.031KN/m
Calculation of the beams and columns
Basic information:
1:height:7.2m;
2:model:Socle beam;
3:load type:concentrated load;
4:length:L=6510mm;
5:width:B=6841mm;
6:design material class:Q235 or above;
Stress analysis of struture
Axial force:
T1: PT1=155N
SC1: PSC1=663N
BR1: PBR1=78N
SB2/SB3: PSB2/3=511N
Maximum bending moment of the post:
Mmax:Design value of maximum bending moment in socle beam(N·mm);
x:distance between the fixed point and the point of maximum bending moment;
L:total length(mm);
a、b:Length parameter(mm);
computing result:
x=0mm
|Mmax|=8097
