ABSTRACT
Four beams with two different beam depth have been tested, The beam depth and the span length have been varied so that they are three times greater for beams of type A than for beams of type B, Fig. 1 and table 1. The longitudinal tensional reinforcement ratio is the same for both beam types. The beams have no compression reinforcement in the rotational zone. All of the beams have vertical stirrups with 200 mm spacing along the whole beam length.
