REINFORCEMENT OF STEEL CRANE BEAMS DURING TECHNOLOGICAL PROCESS MODERNIZATION
The article considers variants of possible reinforcements of split steel crane beams with a span of 6 and 12 meters in the building of an operating industrial enterprise in Nizhny Novgorod in connection with the replacement of crane equipment of 10 tf to 50 tf. Taking into account the constrained conditions caused by the existing technological process, design solutions have been developed to strengthen two types of crane beams with a calculated justification of all design decisions made that meet the requirements of existing building rules. The proposed reinforcement options have been fully implemented in accordance with the developed design documentation and operated under new technological loads since 2020.
