“…[3] have built a unique bend testing machine for low cycle fatigue tests in order to obtain very large cyclic strains. Their very low cyclic fatigue life results for a structural steel are in agreement with Dusicka et al [2]. It was also concluded that the fatigue life predicted by PalmgrenMiners rule together with Manson-Coffin´s relationship grossly overestimates the actual life in extremly low cycle fatigue.…”

“…Dusicka et al [2] tested five different structural steels with static yield strength between 100 and 485 MPa under cyclic plastic uni-axial straining in the range ±1 % to ±7% strain amplitude. Cyclic hardening was observed in all steels and the maximum cyclic stress was found to be dependent on the steel type and the strain range.…”

In integral abutment bridges clamped abutment piles are in addition to a compressive normal force subjected to bending load cycles from daily and yearly temperature variations. Through experiments with full-scale specimens representing a clamped pile it is shown that a steel pipe pile loaded in bending can withstand several hundred load cycles at strain ranges greater than 6 times the yield strain with almost full load bearing capacity. By means of an example it is shown that by permitting pile strains greater than the yield strain, in contrast to most present design codes, integral abutment bridges can be erected with a span length up to 500m and a prospected service life of 120 years

“…Dusicka et al [25] investigated the inelastic cyclic behavior and low-cycle fatigue life of plate steels with the nominal yield strength up to 485 MPa. Ramberg-Osgood model was used to fit the experimental skeleton curves and the associated coefficients were obtained from data regression of the test result.…”

ABSTRACT:Since recent advances of technology in material science and increasing demand for high strength materials, high-strength steel (HSS) has been applied to several landmark buildings and major projects. However, the application of high-strength steel in seismic structures is limited by the relative worse ductility, which usually decreases with the increase in yield strength. In this paper, key issues associated with the application of HSS in seismic structures are pointed out and discussed. The current state of the art of behavior of HSS and recent research on the seismic behavior of HSS carried out at Tongji University are presented. The effect of reheating and cooling during fabrication process on the mechanical properties of HSS is evaluated. Through the revisit and reconsideration on the basic level of seismic design philosophy, two new design methodologies for application of HSS structures for buildings in seismic zones are proposed. Finally, future works related to the application of high strength steels are recommended.

The deformation capacity of steel structures subjected to seismic or other repetitive loadings depends on structural configuration, member and connection characteristics, as well as on the cyclic response of material. While monotonic response of steel is generally available from standard tensile tests, information on response of steel under low cycle and extremely low cycle loading is limited. For numerical analysis, a basic option to determine the steel structures response is to use the tensile properties affected by a calibrated damage of the material. The literature offers several models for more rigorous analysis but these models are more reliable if their calibration is based on experimental results. Experimental results are found in the literature but mostly for low strain cycles. In the case of higher strains, the testing procedure, including the testing machine, requires supplementary support to avoid lateral displacement of the machine cross-head which makes these tests more difficult to be performed. A dedicated device for the cyclic loading was designed against lateral displacement of the machine cross-head. In comparison to the tensile test specimen, the cyclic test specimens have a shorter calibrated length. The paper presents the results of an experimental research on four European steel grades (S275, S355, S460 and S690) subjected to cyclic loading with constant and variable amplitudes. The specimens were tested with a universal testing machine of 250 kN under quasi-static strain rate. The results emphasize the stress-strain curve, number of maximum cycles for constant amplitude, maximum strain for variable amplitude and hardening or softening for the steel response to cyclic loading. Based on experimental data, parameters for modelling cyclic response of steel in Abaqus were determined.
