Breviar calcule :

Sa se proiecteze o hala metalica amplasata in portul Agigea Sud din Constanta cu dimensiunile :- deschideri D- travei T- acoperis in 2 ape

n=14n(D)=R(n/2)+1n(D)=1n(T)=R(n/3) +4n(T)=6D=25000+1000R(n/5)=29mPentru o deschidere de 29m vom lua L D=15mt=6000+1000R(n/3)t=8mh=6000+1000R(n/9)h=6.5m
