I have to design transfer beams of a farm house , the beams are supported on 9" walls and have to support one story circular columns above . I am taking the width of beams equal to dia of columns, I have uploaded the case figure the red colour columns are the columns above transfer beams and are not coming from foundation. I am not sure of reinforcement at which I am designing the beams, if anyone have relevant experience or can guide me regarding design of these beams please help me . Thanks in advance to all respectable seniors and professionals. Should I have to take depth more than normal beams for these beams and which criteria for steel design of thes beams should I follow ?

I am working on design of steel pedestrain bridge design connecting two buildings, the bridge is of L shape and need to provide connection between two trusses if my respected seniors have relevant experience then please share or if not then please guide me what considerations have to kept in that case . I will be obliged 1)The bridge will stay on concrete columns of 1'x1' is this size will be sufficient ? 2) is the connection between two trusses will be safe ,no vehicular load will be there in bridge only for humans The dotted line in fig is the case , the length of one side bridge is of 13ft , the square rectangles are the columns already existing. I will be greatfull for any reviews and help in this case Thanks
