Description

{Seismic Retrofit PC Wall Panel for RC Frame, Seismic Retrofit Structure of RC Frame using PC Wall Panel and Construction Method Using Seismic Retrofit PC Wall Panel for Seismic Retrofit of Reinforced Concrete Frame }

The present invention relates to a reinforced concrete frame seismic reinforcing PC wall which can naturally form an opening for a window or the like to maximize an open area while allowing easy connection with a conventional reinforced concrete frame and maximizing seismic performance with efficient stress transmission Panel, PC wall panel, and its construction method.

Buildings built prior to 1988 when seismic design was introduced, or existing low - rise buildings without seismic design provisions, require seismic strengthening. Especially, as the frequency and progress of earthquakes in recent years have increased, it is urgent to strengthen the earthquake resistance of public buildings used by many people such as school buildings.

Conventionally, as shown in FIG. 1, a reinforcing method for reinforcing a reinforced concrete structure with a reinforcing material such as a steel plate has been developed. However, since the joint between the reinforcement and the reinforced concrete structure is fragile, the seismic performance is degraded, and there is a problem that the usability is deteriorated due to the open feeling due to the interference between the reinforcement and the window.

Accordingly, the present applicant has proposed a remodeling earthquake-proof reinforcement joint structure utilizing a PC member having a sufficient open area using the PC member shown in FIG. 2 and having an excellent seismic strengthening capability of a reinforced concrete structure, and a remodeling construction method Have been filed and registered. The PC member is provided with a steel panel member on the side of the PC member for engagement with the column or beam. The steel panel member is coupled to the column or beam through the anchor member. However, since the PC member is indirectly coupled through the steel panel member rather than being directly coupled to the column or the beam, there is a problem that the seismic performance is deteriorated when the steel panel member is deformed or damaged. In addition, since the steel panel member protrudes to the outside of the PC member, it is inefficient in terms of the transportation and loading efficiency of the PC member, and the steel panel member, which is a steel member, is exposed to the outside, .
