General Design Data

Six-story (changed to three-story) frame, with a full frame, a building without a basement has dimensions in terms of 55, 5x17.1 m and a grid of columns 5, 7x5.55 m. Floor height 3.6 m. Standard value of time load 5.1 kN/m2, private factor for time load. Grodno construction area. Class on a condition of operation of XC4.

Concrete and

reinforcement characteristics

We accept the class of heavy concrete C 30/37 and the class of reinforcement S500 is adopted in the same way as for the girder.

Combination of design forces 1: max M = 57.346 kN· m N = 559.269 kN, and combination 2: max N = 1132.264 kN and moment M = 2.941 kN.
