To increase the strength of the stiffness diaphragm, the doorways are not arranged symmetrically in height, i.e. in staggered order. Thus, excessive flexibility of the diaphragm is partially eliminated. To perform the calculation of such an irregular system relative to the openings causes a certain difficulty and from that we have implemented an elementary calculation. The design scheme was considered as a multi-story frame, for the action of horizontal wind load and floor-by-floor two-span beams with variable cross-sections on hinged supports for the action of vertical loads. The tasks were solved by the force method and graphoanalytically. Methods for determining the bending stiffness of the diaphragm from various loads are considered.
