Item type:Article, Access status: Open Access , Analiza wytrzymałościowa stropu będącego w kontakcie dwuparametrowym z pokładem przy eksploatacji na zawał(Wydawnictwa AGH, 2008) Paluch, Marian; Tajduś, AntoniThis work is a development for T. Ozog's theory by introducing two-parameter Wieghardt's contact. The formulas for beam deflection, reaction of foundation, bending moments, shear forces and the elastic energy of the cantilever beam are derived and discussed. The failure limit of the cantilever span is also calculated.Item type:Article, Access status: Open Access , Wyznaczenie ugięć i sił przekrojowych w stropie będącym w kontakcie dwuparametrowym z pokładem dla wyrobiska korytarzowego(2008) Paluch, Marian; Tajduś, AntoniThe paper presents the equations for calculating deflections, bending moments, and shear forces in the roof connected with the seam by two-parameter contact. The formulas for elastic energy and critical length of opening were also presented. The solution is applied to solve a practical example.
