Summary: Concrete is one of many quasisibrittle materials whose response changes from quasi-plastic to quasibrittle as the ratio of structure size to material inhomogeneity size increases. In consequence, a rational size effect factor must be introduced into the limit load equations of design codes. After reviewing some failures of large structures documenting the size effect, Bažant discusses the recent efforts to modernize the code provisions for beam shear, punching, torsion, plain flexural strength, etc., and explains the benefits for safety, efficacy and innovation friendliness in structural design. Presented in English.
