Behavior of precast concrete beam-to-column connection with U-and L-bent bar anchorages placed outside the column panel- Analytical study

摘要

In an effort to obtain a more comprehensive description on the behaviour of a beam-to-column precast reinforced concrete connection, a model to simulate the hysteretic behaviour of the cyclic response of the connection will be presented in this paper. A mathematical model employed, which uses finite-element approach and takes into account the pinching effect that often occurs in a concrete structure, are employed. Numerical implementation and adaptation of the model obtained in a spring element will be done with the computer code SeismoStruct. A series of numerical data and calibrations are input to produce an adequate response history. While not exactly the same, the model gives result showing good conformity with the experimental data.
