Energy-active expansion segments of halls with structural covers
|Published in:||Budownictwo i Architektura, June 2013, n. 2, v. 12|
The paper presents the results of developing a concept of economical energy-active expansion segments for large-volume halls, in which: 1) structural coverings were used, 2) thermal impacts on forces and displacements were reduced to conventional values stated in the code , 3) load bearing capacity and reliability, greater than those recommended for RC2 class structures, were maintained , 4) the static scheme was selected in such a way so that failure-causing thermal impacts would not affect the reliability of the hall expansion segments. The effect was obtained by detaching the beam kinematically admissible failure mechanism from the tilt kinematically admissible failure mechanism of separate energy-active expansion segments of the hall.
