For buildings not meeting the safety criteria specified by TEASPA, NCREE recommends several retrofit techniques such as construction of shear walls, wing-walls, and column-jacketing. Among these techniques, column-jacketing is usually preferred by school officials due to its less obstruction to both ventilation and natural light. Unfortunately, the structural benefit provided by column-jacketing drops quickly as building height increases. One way to resolve this problem is to connect adjacent jacketed columns with additional beams constructed between floor levels. As preliminary analysis indicated that such measure will greatly improve the effectiveness of column-jacketing, a quasi-static experiment on three full-scale specimens was conducted for verification. Result of the experiment shows that the lateralforce resistance of the retrofitted frame is significantly increased, making the proposed technique a worthy option for the seismic retrofit of concrete buildings
