THE EFFECT OF FREEZE/THAW CYCLES ON THE PERFORMANCE AND MICROSTRUCTURE OF CEMENT-TREATED SOILS
(American Society of Civil Engineering, 2016-12)
In this paper, the performance and structural changes in cement-treated soils under influence of freeze/thaw (f/t) exposure are investigated. Specimens from plastic and compacted soil-cement mix designs were exposed to ...
Bond-Slip Analytical Formulation toward Optimal Embedment of Concrete-Filled Circular FRP Tubes into Concrete Footings
(American Society of Civil Engineers, 2010-03-15)
This paper presents a robust analytical model for a moment connection of concrete-filled fiber reinforced-polymer (FRP) tubes (CFFTs) to concrete footings. The CFFT connection is based on a simple approach of direct embedment ...
Experimental Study of Rectangular RC Columns Strengthened with CFRP Composites under Eccentric Loading
(American Society of Civil Engineers, 2010-01-28)
This paper presents the results of experimental studies on reinforced concrete columns
strengthened with CFRP composites under combination of axial load and bending moment. A
total of seven large-scale specimens with ...
Durability of Concrete Beams with Bonded FRP Composites made of Flax and Glass Fibers
(CSCE, 2016-08-24)
Synthetic fibers, such as glass fibers, in the form of fiber-reinforced polymer (FRP) composites have been extensively used for the repair and strengthening of existing concrete structures in the past three decades. As ...
Durability of Flax FRPs Exposed to Accelerated Environmental Conditions
(CDCC 2017, 2017-07-19)
It is well known that synthetic fiber reinforcements, such as glass fibers, elevate the mechanical properties of polymer materials. Considering the synthetic material’s renewability challenges, natural fibers, such as flax ...
Strengthening Concrete Columns using NSM CFRP Laminates
(6th Asia-Pacific Conference on FRP in Structures, 2017-07-19)
In this paper, the performance of concrete columns strengthened with longitudinal near surface mounted (NSM) carbon fiber-reinforced polymer (CFRP) composite laminates is evaluated. A total of fourteen medium-scale plain ...
Snowmelt infiltration and macropore flow in frozen soils: overview, knowledge gaps, and a conceptual framework
(Soil Society of America, 2018-11-08)
Macropore flow in frozen soils plays a critical role in partitioning snowmelt at the land surface and modulating snowmelt-driven hydrological processes. Previous descriptions of macropore flow processes in frozen soil do ...
Performance of High-Modulus Near-Surface-Mounted FRP Laminates for Strengthening of Concrete Columns
(Elsevier, 2019-05-01)
This study investigates the performance of high-modulus near-surface-mounted (NSM) fiber-reinforced polymer (FRP) laminates in strengthening of existing concrete columns. The focus of this study is on the compressive and ...
Fillet welds around circular hollow sections
(Springer, 2019)
A research program was conducted to evaluate the safety of design rules for fillet
welds around the perimeter of steel circular hollow sections (CHS) in the current
American Institute of Steel Construction (AISC) steel ...
Numerical Analysis of Longwall Mining Layout for a Wyoming Trona Mine
(Elsevier, 2016)
At Solvay Mine, located in southwestern Wyoming, a subhorizontal trona seam is mined at depths of between 460-490 m using mechanized room-and-pillar and longwall mining methods. The stratigraphy at the mine generally ...
