Hi there,
I want to set a LM1 load model into my bridge. I have defined national lanes and load case but there is one issue that does not give me peace of mind.
I wrote this kind of code:
+PROG SOFILOAD urs:28.4
HEAD LM1 DEF
ECHO LOAD extr
LET#DIR ‘R’
LET#W 3.0
LC no 31 type none TITL ‘LM1’; TRAI type LM1 DIR #DIR WIDT #w P1 300
end
+PROG SOFILOAD urs:24.5
HEAD Load LM1 Stepping
ECHO full no
ECHO LOAD extr
loop#i 60
lc no 70+#i type none titl 'LM1'
copy no 31 type grU ref 'AXIS.11' dx (#i*(90.79/(60-1)))
endloop
END
As you can see I set a type grU which will take into account vertical loads (TS+UDL) and here is my main question. When I create a combination rule then I have to adjust type of action for this load but L_T(TS) and L_U(UDL) have a different coefficients. How to deal with it to be sure that Sofisik will apply correct coefficients for TS and UDL if both of those loads are stored in one loadcase?
