Evaluating Method of Deformation at Losing Point of Axial Load Carrying Capacity of RC Columns

“…In this section, the authors provide a summary of the equation for evaluating the lateral deflection angle at the axial capacity point for RC columns failing in shear, which was proposed by Kato et al in 2006, and shown here.…”

“…The axial load P fr,cal for calculation was empirically obtained using experimental data. Kato et al (2006), and the test data for the P and H series were reported by Kato et al (2004) in English. The test results include the lateral deflection and axial deformation at the axial capacity point, which were defined as maximum values observed during the loading tests.…”

“…For this purpose, some studies have been performed on the axial load carrying capacities of RC columns (Pujol et al (2000), Moehle et al (1999), Nakamura et al (2002)). The authors also conducted static loading tests on RC columns failing in shear and proposed an equation for evaluating the lateral deflection angle at the losing point of the axial load carrying capacity (Kato et al (2006)). The "losing point of the axial load carrying capacity" is defined as "the point where a column specimen cannot sustain the scheduled constant axial load during the loading test," and it is sometimes abbreviated as the axial capacity point in this report.…”
