The picture shows the supporting beam of the office building and its load. The design value MEd of the bending moment must always satisfy the condition STR in the ultimate limit state MEd/MRd 1. Determine and draw the load combination from which the design value MEd of the bending moment can be calculated in reliability class RC3 a) with support B b) in the middle of the field AB (not a critical point of the structure, but easy to calculate) A 10 kN/m pysyv kuorma 20 kN/m muuttuva kuorma 8,0 m 20 kN muuttuva kuorma B 2,5 m C
