An Autoclaved aerated concrete (AAC) masonry is an efficient structural system because its light weight resulted from its material characteristics by its own cellular str [...]

Currently, RC structure including beams with secondary walls and influences of these walls are ignored in Japan, because they are considered as non-structural elements ha [...]

Mechanical anchors are generally used to terminate the beam longitudinal bars at an exterior beam-column joint of reinforced concrete high-rise buildings in Japan. In the [...]

This paper was written about the deterioration of the shear strength capacity and the failure mode of columns subjected to high fluctuation axial force. Four columns desi [...]

The purpose of this research is to calculate the center of rigidity in the non-linear range of eccentric structures. It is necessary to calculate the equivalent stiffness [...]

The objectives of this study were to investigate the hysteresis characteristics, shear transferring capacity, damage state and possibility to disassemble the precast unbo [...]

The authors are developing a new retrofitting system for relatively low seismic performance existing buildings, especially for soft-first-story buildings. The new column, [...]
