This dissertation analyses precast walls made of plain concrete and lightly reinforced concrete. The main focus is on evaluating the concrete and the reinforcement of precast concrete wall panels in relation to manufacturing, handling, and final phases. The dynamic load component of panels during handling was measured in controlled tests. Shrinkage measurement was implemented during the maturing process of the concrete used for panel manufacturing. The value of cohesion was observed between the reinforcement and the concrete that had matured for 20 hours. It was also looked at the value of adhesive strength between the panel surface and the casting table. The experimental study checked the panel strain during removal from the casting table, the panel compression during a truck ride over an obstacle, and the tension in the carriage strap during panel transportation to the building site. Mathematical formulas were drawn up to validate the concrete and reinforcement of wall panels made of lightly reinforced concrete. Those mathematical formulas were applied in a specific panel wall design and the results were verified by nonlinear numerical models.
