Description

Frame construction method including reinforcement method {METHOD FOR FRAME CONSTRUCTION}

The present invention relates to a reinforcement structure and a method therefor, and more particularly, to a frame construction method including the same.

According to the current KBC2009 standard (building structure design standard), when constructing a high-rise building over 60m that falls under seismic design category D, the height limit rules apply, and it is stipulated that construction is possible only when special shear wall structures and special details of connecting beams are applied. have. In this case, special reinforced concrete connecting beams with a span/dance (ln/h) ratio of 4 or less are used to bear all shear force by using diagonal bundled reinforcing bars. Here, the diagonal bundled reinforcing bars consist of at least 4 reinforcing bars, and they are also reinforced with transverse reinforcing bars in the same way as the transverse reinforcement rules of columns.

In terms of securing structural performance, the details of reinforcement of connecting beams must be observed. However, since diagonal bundled reinforcing bars using transverse reinforcement are mutually reinforcing in the central part of the connecting beam, it is difficult to reinforcing reinforcing bars due to the mutual interference problem.
