4. VĒJA SLODZE
• Fundumentālais vēja pamatātrums vb,0=21 m/s
• Koeficients F = 1.5
• Vēja spiediena pamatvērtība qb (v = 21) = ½ • 1.25 • 212 = 0.28 kPa
• Z=h=12m
• Interpolējot iegūst, ka Ce(z) = 1,81
• Pīķa ātruma spiediens qp(z):
qp(z) = Ce(z) • qb = 1,81*0,28 = 0,5068 kPa
• Tā kā h=12m < b=48m, tad qp(z) = qp(ze)=0,5068 kPa
• h/b = 12/48 = 0,25
• Tā kā S=12*48=576>10m2, izmanto Cpe10 vērtības:
D zonā - Cpe10 = +0,7
E zonā - Cpe10 = -0,3
• Lineārās vēja spiediena vērtības uz fasādēm:
D zonā :
We,k=We*B= qp(ze)* Cpe10*B=0,5068*0,7*12=4,257 kN/m
We,d= We,k*F=4,257*1,5=6,386 kN/m
E zonā :
We,k=We*B= qp(ze)* Cpe10*B=0,5068*(-0,3)*12=-1,824 kN/m
We,d= We,k*F=(-1,824)*1,5=-2,736 kN/m
