Re: STEEL ROOF Hello; At the end of the sloping end of the roof, will the lower end of the beams be consoled in this way or will it be supported by another element in the structure, if it will be connected to reinforced concrete columns, if you connect these beams by entering a steel column with a length of 50-60 cm in between, the structure will exhibit a more appropriate behavior, currently 1.mod 3.2 sec. looks. You have also entered the auxiliary elements with a single sub-beam command. However, there is no flooring on it. In order to enter the loads on them, model these elements again by using the purlin command instead of the 1-single sub-beam command. Then make a coating entry on the purlins. 2- Enter the required fixed, mobile and snow loads in the loads section of the coating settings. Good work.
