Stūra šuves katetis Kf:
K_f=1,4∙a=10,543 mm
5 mm≤10,543mm≤t_1
5 mm≤10,543mm≥10 mm – nosacījums neizpildas, jo šuves katetes lielums ir lielāks par plāksnes biezumu, gar kuru metinātā šuve ir orientēta.
l_w=b-2a=220-2*7,531=204,94 mm
〖τ_(w,Ed)〗^([N])=N/(l_w∙a)=180/(204,94∙a)=0,878/a kN/〖mm〗^2
〖τ_(w,Ed)〗^([V])=V/(l_w∙a)=150/(204,94∙a)=0,732/a kN/〖mm〗^2
〖τ_(w,Ed)〗^([M])=M*z/I_y =M/W_y =6M/(a*〖l_w〗^2 )=(6*4*10^3)/(a∙〖204,94〗^2 )=0,571/a kN/〖mm〗^2
τ_(w,Ed)=√((〖τ_(w,Ed)〗^([M])+〖τ_(w,Ed)〗^([N]) )^2+(〖τ_(w,Ed)〗^([V]) )^2 )
τ_(w,Ed)=√((0,571 /a+0,878/a)^2+(0,732/a)^2 )=1,68274 kN/〖mm〗^2=1682,74 N/〖mm〗^2
1682,74/a=208,8
a=1682,84/208,8=8,059 mm - a≥a_min=3mm nosacījums izpildas.
