Abstrait:

Rational design approach for reinforced concrete beam under combined bending and shear needs to be developed, since they always occur simultaneously. Based on the Thurlimann’s fully-plastic stress field model, a parabolic envelope and an additional limitation for intensive shear capacity is derived. Then, a simplified flexural-shear design method for concrete beams is proposed suitable for different reinforcement layout, which is illustrated by a working example. It has to be admitted that the parallel cracked model is more applicable to shallow beam, for cracking pattern in small shear-to-span ratio regions is quite different. In addition, the ductility of reinforcement must be ensured to prevent possible brittle premature failure.
