Plastic Mechanism and Elastic Analyses in the Strength Estimation of an Axially Compressed-Thin-Walled Channel Steel Section Beam
Channel section local buckling plastic mechanisms effective width moment capacity and axial-compressive strength
2009/2/18
This paper presents the study of an analytical model to estimate the strength of a thin-walled channel steel section beam subjected to axial-compressive loads. The model is based on two different meth...
his paper presents a plastic mechanism analysis for circular hollow section (CHS) tubes strengthened using carbon fiber reinforced polymer (CFRP) deforming in an axi-symmetric (elephant foot) collapse...
MECHANISM OF DAMAGE TO SHIWEI BRIDGE CAUSED BY 1999 CHI-CHI EARTHQUAKE
Chi-Chi Earthquake failure of structure concrete pier earthquake damage
2009/1/6
The Shiwei Bridge in Taiwan was extensively investigated in order to determine the reasons for its failure during the 1999 Chi-Chi Earthquake. Our field investigation revealed no evidence of horizont...
HOW TO INFER THE POSSIBLE MECHANISM AND CHARACTERISTICS OF EARTHQUAKES FROM THE STRIATIONS AND GROUND SURFACE TRACES OF EXISTING FAULTS
acceleration earthquake characteristics fault focal plane solutions magnitude striation
2009/1/6
The instrumented period for earthquakes is relatively short to understand their mechanism and characteristics in many countries. Even at present time, there are many areas in the world where seismic i...
FBG STRAIN SENSOR WITH SIMPLE TEMPERATURE COMPENSATION MECHANISM
FBG sensor strain measurement temperature compensation
2008/12/25
A FBG-based strain sensor equipped with a mechanical temperature compensation system is proposed. Direct bonding of a FBG element may cause broadening of the reflected optical spectrum due to fluctua...
COMPRESSIVE FAILURE MECHANISM OF DFORMED CONCRETE TUNNEL LININGS DUE TO A VERTICALLY CONCENTRATED LOAD
ground pressure cracking compressive behavior parabolic compressive softening model
2008/12/25
Concrete tunnels subjected to the ground pressure usually show a compressive failure mode. Moreover, due to an unbalanced soil constraint, deformed tunnels under an additional concentrated load will ...
INFLUENCE OF FAULT MECHANISM, DEPTH, AND REGION ON STRESS DROPS OF SMALL AND MODERATE EARTHQUAKES IN JAPAN
stress drop fault mechanism crustal earthquake interplate earthquake intraplate earthquake
2008/12/22
Stress drops of 168 earthquakes (focal depth ≤60 km, 4.4≤MW≤6.9) are estimated by a generalized-inverse method using strong motion records in Japan. Stress drops of crustal earthquakes are dependent o...
Analysis of mechanism on water-reducing effect of fine ground slag,high-calcium fly ash, and low-calcium fly ash
Workability Admixture Cement paste Fly ash Granulated blast-furmace slag
2007/7/9
The addition of ultrafine powde（UFP）to concrete can improve the fluidity of concrete，showing a water-reducing effect. The aim of this article was to analyzi the water-reducing mechanism of UFP both ex...
