ACI SP-123:1991 PDF Download

The ACI SP-123:1991 standard consists of a collection of technical papers that provide guidance on the design of beam-column joints to enhance their seismic resistance. The volume contains a total of nineteen papers classified into five groups.

The first group includes four papers that present test results conducted on specimens designed using current codes, but with the same general geometry and a specified loading history. These papers aim to evaluate the performance of beam-column joints under seismic forces and examine their behavior under different loading conditions.

The second group consists of one paper that discusses design recommendations specific to beam-column joints in Japan. This paper provides insights into the design approaches adopted in Japan to ensure the seismic resistance of these joints.

The third group comprises eight papers that investigate the influence of joint geometry on the strength and deformation characteristics of beam-column joints. These papers explore the effect of various factors such as joint size, detailing, and reinforcement on the overall performance and seismic resistance of the joints.

The fourth group includes four papers that focus on the influence of bond on the performance of beam-column joints. These papers examine the bond behavior between concrete and reinforcement in joints, highlighting its importance in enhancing the seismic resistance of the joints.

The final group consists of two papers that address the design of beam-column joints in precast systems and those using high-strength materials. These papers explore the specific considerations and design strategies required for these types of joints to ensure their seismic resistance.
