Abstract
Proper anchorage of beam reinforcement in beam-column joints is necessary for a stable hysteretic behavior of seismically loaded structures subjected to large lateral displacements. Anchorage requirements associated with the use of higher strength steel such as S500 generated the need to increase the anchorage lengths and concrete strengths. Formerly used concrete strength classes such as C20/25 and C25/30 are largely replaced with higher quality concrete such as C40/50 or more. In common design practice, anchorage provisions of the repealed Romanian standard STAS 10107/0-90 are still informally used. This might lead to poor anchorage details and related structural problems. This paper draws attention on the specifications of the current standards for anchorage of beam reinforcement. Practical design rules are presented as well.
