PROBLEM TO BE SOLVED: To provide a reinforcing structure for a hybrid beam that enhances workability when reinforcing a reinforced concrete beam through which a horizontal equipment hole is opened, the hybrid beam absorbing earthquake energy and having an equipment hole that helps enhance its durability.SOLUTION: An equipment hole 20 is opened through a reinforced concrete beam 10B close to a column 12, horizontally through the reinforced concrete beam 10B. The equipment hole 20 pierces through both side surfaces of the reinforced concrete beam 10B, and is formed by an inner peripheral surface 2202 of a steel pipe 22 unified with the reinforced concrete beam 10B. |
