The present invention relates to a method to improve a sectional resistance force on a negative moment applied to an end of a beam in case of repair, reinforcement, or remodeling. The method to improve the sectional resistance force on a negative moment applied to the end of the beam efficiently and easily improves a resistance force on a negative moment applied to the end of the beam using an end reinforcing member in a structure wherein the end of the beam is connected to a structure such as a column by moment connection. The sectional resistance force is improved as the beam and the end reinforcing member have a composite section, and a neutral axis moving downwards. As such, the method to improve the sectional resistance force on a negative moment applied to the end of a beam is able to efficiently be used for the repair, the reinforcement, or the remodeling of a building. The method to improve a sectional resistance force on a negative moment applied to an end of a beam comprises a step of installing the end reinforcing member connected to a lower surface of the end or to the lower part in a longitudinal direction of the beam. |
