摘要

the way is another implementation of: - before welding, the lower belt (3) to the semi colon (2) previously combined with upper belt (1), a cross-section of the central blachownicy apply at least three sensors tensometryczne (t), two of which on the upper (1) and the other on u015brodn cookie (2) below a horizontal axis (x - x) neutral section.then, the lower belt (3) extends with a tensile stresses of 60 - 90% calculated tensile stresses qmax at maximum load blachownicy and maintaining the weld strip bottom (3) to a web height (2) - after ostygniu0119ciu blac hownicy, under the load burden own qw beamson the basis of the indications tensometrycznych sensors (t) is determined by the transition aistowa value internal forces and provides compressive stress? c in the bottom (3) and accordingly the difference? ? c between calculation stress qmax tractive and compressive stress. c,what - for the difference of stress? ? c identifies the location and dimensions of pre contact (4) and connecting them with a bottom (3) of welds and welding the contact 36 is made (4) to the lower belt (3) symmetrically about the vertical axis of symmetry (y - y) blachownicy.
