Mechanical splices are sometimes installed incorrectly in a construction site when the centers of two steel bars are deviated. As a result, the steel bars are not embedded sufficiently in a coupler. RC members using such mechanical splices cannot achieve properties as expected. This paper shows mechanical behavior of such mechanical splices and RC beams using them. A numerical model for analyzing RC members using insufficiently embedded mechanical splices is also presented. The developed model, which bases on the well-known fiber model, is validated using the experimental results.
