ABSTRACT
This article presents the results of experimental and theoretical studies of the operation of
inclined sections of bending elements operating under the influence of one-sided heating. A
method is proposed for calculating such structures for transverse forces, taking into account the
actual stress-strain state of the element.

INTRODUCTION
When designing bending reinforced concrete structures of thermal units, special attention is paid
to their calculation for the effect of transverse forces, since these structures often have short
lengths and large transverse forces arise during operation. The calculation of bending reinforced
concrete elements operating under conditions of high and high technological temperatures on the
shear force is being improved as experimental and theoretical research is accumulating.For this
purpose, special experiments were carried out on bending reinforced concrete elements made of
ordinary and heat-resistant concrete under the action of transverse forces under conditions of
exposure to one-sided heating. The experiments were carried out on reinforced concrete beams
of rectangular cross-sections 16x30cm and length 240cm. Beams were made from ordinary
heavy concrete of class B 35 on Portland cement with granite crushed stone and quartz sand and
from heat-resistant concrete on alumina cement with fireclay aggregates of class B35.
