WebA review of current code requirements on lap splices and their limitations in seismic design is presented. A simple analytical model of an embedded bar is examined and correlated with available experimental data. The force transfer mechanisms of lap splices and the effects of properly placed transverse reinforcement to avoid brittle failure are studied.

WebAug 1, 2024 · 1. Introduction. In most regions of the developed world, the building stock has already started to age considerably. Within the European Union for example, 80% of the buildings were built before the 90's, 40% before the 60's, with a third of buildings over 50 years old [1].The impact of the old building stock on the environment is huge as buildings … WebApr 26, 2012 · The provisions for the required development length, splice length, hooks and bend diameters are compared for the 1956 ACI code, 1963 code, 1971 code, 1989 code and the current code. It is shown that the development lengths and splice lengths have increased significantly since 1956.
