This paper is concerned with analysis for the strengthening effect of carbon fiber-reinforced polymer (CFRP) on steel columns under cyclic lateral loading in thermal environment. Based on the finite element theory of thermo-elastic problem and steel structure stability theory, the hysteretic behavior of axial compression steel columns was studied by using Ansys software. The main variables inve...

Li: College of Materials and Metallurgy, University of Science and Technology Liaoning, Anshan City, China Hollow side wall insulation mathematical model of unidirectional solidification temperature field was carried out. With the aid of finite element analysis software ProCAST, directionally solidified ingot temperature field with hollow lateral wall in...

of bridges are typically based on simplified analyses or empirical data from recent earthquakes. Since earthquake damage data are very scarce in the central and southeastern United States (CSUS), using analytical methods is the only feasible approach to obtain fragility curves. In 1990, bridges in the CSUS began incorporating seismic details. Some of the changes included the component design fo...

The field emission properties and the vacuum measurement application are investigated from the multi-walled carbon nanotubes (MWNTs) grown directly on catalytic stainless steel substrates. The MWNT emitters present excellent emission properties after the acid treatment of the substrate. The MWNT gauge is able to work down to the extreme-high vacuum (XHV) range with linear measurement performanc...
