Title: A New AIJ standard for Seismic Capacity Calculation: Recent Advances in Beam-Column Joint Design and Seismic Collapse Simulation on Reinforced Concrete Frame Buildings
Author(s): Hitoshi Shiohara
Publication: Special Publication
Appears on pages(s): 1-10
Keywords: Seismic, design, concrete, beam-column joint
Abstract:A new concept of joint hinging developed in Japan is presented, which will be implemented in a new draft provision for beam-column joints in the New AIJ (Architectural Institute of Japan) Standard for Seismic Capacity Calculation. This paper discusses the key issues of the new draft provisions, with
background, test data verification, theory and analyses with emphasis on why such a concept is necessary. The factors affecting joint hinging failure are discussed for seismic design consideration. Seismic collapse simulation were made by non-linear time history analysis for moment frames with BC joints failing due to joint hinging, to demonstrate the challenge of simulated strength degradation and severe pinching
hysteretic behavior inherent to joint hinging. Draft equations to calculate the strength of joint hinging strength of BC joints are also introduced.
