Seismic performance of double-channel and double-HSS sections, special truss moment frame with buckling restrained braces, and long span Special Truss Moment Frame
(2018-01-10)Until recently, all special truss moment frame (STMF) experimental research was done on only double angle STMFs. In order to satisfy the code seismic drift limitation, especially for mid-rise and tall multistory buildings, ... -
SEISMIC RESPONSE AND DEFORMATION ANALYSES OF EARTHEN DAMS
(2019-12-05)Assessment of the response of earthen structures, such as dams and levees, during earthquake events, is crucially important to geotechnical engineers. It is imperative to perform seismic response analysis to assess the ... -
Selecting A Shaft/pit Construction Method For Trenchless Technology
(Civil & Environmental Engineering, 2012-07-25)The word shaft describes a vertical access point that is created by excavating, vertical boring, or blasting required before the start of tunneling or boring operations. Most trenchless technologies require entry shafts ... -
Selective Catalytic Reduction Of Nitric Oxide Over Cerium-doped Activated Carbons
(Civil & Environmental Engineering, 2014-03-10)Selective catalytic reduction (SCR) with ammonia for diesel engine NOx reduction using activated carbon (AC) was studied. Comparisons of unmodified and cerium-doped Granular Activated Carbon (GAC), Activated Carbon Fiber ... -
SERVICE LIFE PREDICTION AND RISK ANALYSIS OF REINFORCED CONCRETE GRAVITY FLOW PIPES USING RELIABILITY THEORY
(2019-05-15)Reinforced concrete pipes are susceptible to different types of deteriorations that threaten their structural capacity and serviceability. Failure of these structures or losing parts of their operational capabilities may ... -
Settlement Analysis Of Drilled Shaft Foundation On Natural And Lime-treated Compressible Clayey Soil
(Civil & Environmental Engineering, 2014-12)Drilled shaft foundations are primarily used to support structures such as bridge piers, buildings, and transmission towers. The main advantage of a drilled shaft foundation is that it transfers loads to the stronger ... -
Shear Behavior Of Steel Fiber Reinforced Prestressed Concrete Beams Without Shear Reinforcement
(Civil & Environmental Engineering, 2012-04-11)The ACI 318-08 building code allows to use the steel fiber reinforcement as alternative shear reinforcement with satisfying certain criteria when a beam is required minimum shear reinforcement. However, this provision ... -
SHEAR BEHAVIOR OF SYNTHETIC FIBER REINFORCED CONCRETE BOX CULVERTS
(2019-07-19)This research pursues a comprehensive experimental study on the shear capacity of zero-slump, dry-cast Synthetic Fiber-Reinforced Concrete (SYN-FRC) with the aim of reducing or even eliminating stirrups in box culverts. ... -
Shear Investigation of Polypropylene Fiber-Reinforced Concrete Beams
(2017-02-14)This study investigates the effect of macro-synthetic polypropylene fibers on the shear strength and failure behavior of longitudinally reinforced concrete beams with and/ or without transverse reinforcement. Eight large-scale ... -
SLOPE STABILIZATION AND PERFORMANCE MONITORING OF I-35 AND SH-183 SLOPES USING RECYCLED PLASTIC PINS
(2015-12-01)The United States earth retaining structure market exceeds 170 million square feet annually and there are over 50 different retaining systems to select from which are unique in design and construction. Depending on the ... -
Smart Speed Bumps
The research underscores the need and importance of traffic calming devices and provides the basis for designing and building a device for traffic calming in neighborhoods with high pedestrian traffic, particularly children. ... -
SORPTION-MEDIATED CHEMICAL PROCESSES FOR THE VERSATILE TREATMENT OF PER- AND POLYFLUOROALKYL SUBSTANCES (PFAS) IN COMPLEX MEDIA
(2020-08-10)In recent years, per- and polyfluoroalkyl substances (PFAS) have gained notoriety due to environmental and health concerns. These molecules are chemically stable which contributes to their persistence in biological systems ... -
Spatial Variability Models And Prediction Analysis Of Soil Properties Using Geostatistics
(Civil & Environmental Engineering, 2014-12)Soils are composed of solid, water and air phases whose characteristics are highly variable. The interactions of these phases in the soil matrix can lead to different types of topographical formations and characteristics. ... -
