In the last years light concretes filled with artificial porous components are widely utilized in constructional practice. During exploitation constructional elements undergo complicated force's influences. Joint action of bending & rotational forces is an example of such dangerous conditions. In Lviv State Politechnic University we studied the stength of light armoured concrete elements undergoing bending & rotation. Our main task was to investigate the stability of rectangular-shaped armoured with A-III-class armour light concrete elements in conditions of both bending & rotation & single rotation. Resistance of tested elements to deformations & forming of fissures was established. Theoretical calculations were compaired with the results of experimental tests. We offer practical calculations of usually armoured light concrete element's strength in conditions of bending & rotational influences.
