A method for selecting the longitudinal pitch LOCATION supporting column in the free zone of single-storey public and industrial buildings frame structures

摘要

The method of selecting the longitudinal pitch arrangement of pillars in the free zone storeyed public and industrial buildings carcass structure, comprising selecting the transverse pitch of pillars defining the distance between the longitudinal axes and the location of the longitudinal axes, the selection section supporting columns, the determination of the longitudinal axes of equipment size set in the free zone, determining the position of the transverse axis, determining a distance along the longitudinal axes until the first piece of equipment, the distances of the longitudinal axes m waiting for a piece of equipment, the selection limits the longitudinal pitch supporting columns and optimal longitudinal pitch supporting columns, characterized in that the optimal longitudinal pitch supporting columns x is determined according to the formula! ! ! ! where x - longitudinal spacing of columns, m; ! p1 - ​​distance from the lateral axis to the first piece of equipment, m; ! p2, ... pn - the distance between the longitudinal axis of the piece of equipment that intersects the longitudinal axis considered in the order they appear on this axis, meters; ! n - the total number of pieces of equipment intersected by the longitudinal axis of the considered l2, ... ln - dimensions along the longitudinal axis of the equipment units traversed by the considered longitudinal axis m; ! zpr - supporting column size along the longitudinal axis m; ! zpop - supporting column size along the transverse axis m! provided that x tends to the upper limit of the permissible longitudinal pitch supporting columns.
