Abstract: Cyclic tension and compression testing has revealed that cracking behavior in structural steel subjected to plastic strain reversals is transitional from a fatigue to a ductile mode with the elevation of strain amplitude. ...

Abstract: Brittle fracture of structural steel members in buildings is generally triggered by a ductile crack initiated at a notched surface after undergoing a noticeable amount of plastic strain, as evidenced by structural damage ...

Abstract: A method is presented for the inspection and repair of fatigue cracks that occur in the bottom tension flanges of crane runway girders. The date of first inspection and the interval of inspection are determined from fatigue ...

Abstract: A weak‐beam‐strong‐column philosophy is generally recommended for the design of earthquake‐resistant multistory structures, because the associated overall collapse mechanism exhibits a high ductility against a strong ground ...

Abstract: A hypothesis, which is called similitude law of prefracture hysteresis, is advocated in this paper. The similitude law is as follows: the relationships anlong ductility amplitude

Abstract: An ultimate limit‐state criterion is developed for the seismic reliability assessment of single‐story structures. This criterion is: When the structural precollapse energy absorption capacity is greater than the earthquake ...

Abstract: In practice, engineers can usually only obtain material properties from monotonic tensile coupon tests. The aim of this paper is to predict cyclic plasticity of mild steel from coupon test results available. First, the ...

Abstract: This paper aims to predict ductile fracture of mild steel under monotonic loading only from the test results of notchless tensile coupons. A simple fracture model based on the concept of a damage index with only one model ...

Abstract: Extensive research efforts have been devoted to clarifying the causes and their physical relationships of the brittle fracture of steel structures which were observed at the disasters of 1994 Northridge Earthquake and 1995 ...

Abstract: Previous studies have proposed a cyclic ductile fracture model by applying the void growth model and an established rule in incremental form, in which only a monotonic tensile coupon test is required to calibrate the ...
