Behavior of Large-Scale Circular and Square RC Columns Confined with Carbon Fiber-Reinforced Polymer under Uniaxial Compression Zhenyu Wang1, a, Daiyu Wang1, b, Dagang Lu1, c 1School of Civil Engineering, Harbin Institute of Technology, Harbin, China azhenyuwang@hit.edu.cn, bdaiyuwang@hit.edu.cn, cludagang@hit.edu.cn Keywords: CFRP; Confined concrete; Circular columns; Square columns; Uniaxial compression; Stress-strain behavior Abstract: Most experimental studies concerning the stress-strain behavior of concrete columns confined with carbon fiber-reinforced polymer (CFRP) focused on plain concrete columns with small section.
Introduction FRP confinement is a key technique to increase the seismic capacity of RC columns, which are critical structural members that withstand vertical compression and lateral seismic loading [1].
The accurate stress-strain model for FRP-confined concrete is the foundation to use this technical in actual engineering projects.
The properties of steel and CFRP materials are given in Table 2.

The experiments carried out in the study and the subsequent analyses performed on the data rely on an engineering approach and are associated with quantitative measurements.
The issues of measurement in terms of engineering are based on a scientific discipline called metrology [10].

The Modulated Photothermal Radiometry (MPTR) technique was implemented to measure the thermal conductivity of IST thin films as well as the thermal boundary resistance at the interface with other surrounding materials (a metal and a dielectric).
Due to the low thickness of the chalcogenide material in real memory cells, the value of the thermal boundary resistance (TBR) at the interface between theIn-Sb-Teand neighbor materials involved in the PCM cell is comparable to the one of the thermal resistance of the In-Sb-Teitself that is the ratio between its thickness (in the direction of the heat flow) and its thermal conductivity.
During thermal annealing, the thermal conductivity monotonically increased owing to the on- going crystallization of the materials.

Experimentally and theoretically have been proven that the relationship between particles and pore throat sizes are the key factors to the particles migration and plugging [11].
Abrams, [15] proposed that the amount of the particle size of the bridging materials should be at least equal to or greater than one-third of the pore size of the reservoir rock.
The laws that govern nanoscale material behavior are drastically different than the laws governing the macro/micro scale behavior [20].

While the behavior of electrons in particular control most of the properties of materials, the nature and characteristics of every material can be investigated from first-principles, which means grounded on fundamental laws and without any free parameters, by solving the Schrödinger equation for the electrons in that material (based on the Born-Oppenheimer approximation: that the electrons move very fast in comparison to the nuclei that are always more stable, and are so lighter than the atomic nuclei that is feasible to consider fixed the positions of the nuclei while dealing with the electrons)[5].
