Abstract
The article describes the algorithm for probabilistic analysis of reinforced concrete beams made of wood-cement composite for a target reliability level. The reliability index and no-failure probability are used as the indicators for required level of reliability. Experimental studies on woodcement composite beam behavior with steel reinforcement are performed. The presented approach allows to determine the most rational reinforcement based on economic factors and safety level of the object. On the basis of probabilistic algorithms, it is possible to assign tolerances on the dimensions of the beam cross-section and on the location (distance) of reinforcement, based on ensuring the required level of nofailure probability. Reinforced wood-cement composite beam structures can be used as load-bearing and self-supporting lintels, having higher vapor permeability and energy efficiency than heavy concrete lintels. The permissible level of failure probability can be assigned for a group of elements of the objects individually, based on the criterion of acceptable risk.
