Extract

1. Uz balstu un pamatu darbojošos aprēķina slodžu un to kombināciju noteikšana:
Pāļu režģoga pēdas dziļums:
Pieņemu, ka dp = 1 m
Vertikālās slodzes
Fv = P *2 + G + Qb
Balsta svars
VB=Spam*H=(6*1.5+*0.752)*8=(9+1.766)*8=86.128m3
Qb = VB * *1.3=86.128*22.5*1.3= 2519.244kN/m3
Fv=1330*2+8450+ 2519.244= 13629.24kN
Horizontālās slodzes x un y asu virzienos.
Fx = B + F1 =203+21= 224kN
Fy = F2 + F3 = 138.6 +1978.2= 2116.8kN

Lieces momenti ap x un y asīm
Mx ledus AŪL=(1+6.2)*F3aug=7.2*1186.92=8545.8 kNm
Mx ledus ZŪL=(1+1)*F3 zem=2*1978.2=3956.4 kNm
Lielāks ir Mx AŪL
Mx=Mx AŪL+(8.6+1)*F2=8545.8+9.6*138.6=9876.36 kNm
My=(1+3.5)*B+(6+1)*F1=4.5*203+7*21=1060.5 kNm

2. Pieņemu, ka pāļa garums L = 12 m; Šķērsgriezuma izmēri 0.35*0.35…
