Abstract
An analytical model incorporating bending and shear behavior is presented to predict the<br />lateral loading characteristic for rectangular hollow columns. The moment-curvature relationship for the<br />rectangular hollow sections of a column is firstly determined. Then the nonlinear lateral load-displacement<br />relationship for the hollow column can be obtained accordingly. In this model, thirteen constitutive laws<br />for confined concrete and five approaches to estimate the shear capacity are used. A series of tests on 12<br />model hollow columns aimed at the seismic shear behavior are reported, and the test data are compared to<br />the analytical results. It is found that the analytical model reflects the experimental results rather closely.
Key Words
hollow bridge column; shear behavior; seismic behavior; confined concrete; ductility factor; load-displacement relationship.
