Improving the algorithm of choosing spacing and number of stiff supports against a concentrated force in steel-concrete beams

A steel-concrete beam was taken as the study object. The algorithm of selecting number stiff supports for loaded with a concentrated lateral force in middle span has been refined. Stiff served to join steel strip concrete ensure their joint performance. refined based on condition equality longitudinal from action calculated load and maximum obtained after setting supports. In this case, forces all supports, well spacing should be same. disadvantage known consists complexity determining coefficient φb2 taking into account effect long-term creep element deformation without cracks. This fluctuates widely depends many factors. Besides, it is also insufficiently studied. Calculations were conducted according proposed Lira software package. acting support 8941.5 N. When characteristics beam, obtained. amounted 35726 same diagram aimed at improving design beams. rational placement savings: required amount building materials reduced cost due cutting labor costs manufacture operation
