RISGravity Wave Diagnosis Using Empirical Normal Modes
Publisher: American Meteorological Society
Abstract: The theory of empirical normal modes (ENMs) is adapted to diagnose gravity waves generated by a relatively high-resolution numerical model solving the primitive equations. The ENM approach is based on the principal component ...
Gravity Waves from Fronts: Parameterization and Middle Atmosphere Response in a General Circulation Model
Publisher: American Meteorological Society
Abstract: Current parameterizations of the gravity wave processes that are relevant to middle atmosphere general circulation modeling need to have specified somewhere in the lower atmosphere a number of characteristics of the gravity ...
Experimental Study on the Shear Behavior of UHPC-Strengthened Concrete T-Beams
Publisher: ASCE
Abstract: Ultrahigh-performance concrete (UHPC) strengthening is an efficient technique to improve the capacity of shear-deficient members. However, the applicability of UHPC strengthening on a T-beam has been scarcely investigated, ...
Prediction of Moment–Curvature Response and Maximum Bending Resistance for Hybrid NSC-UHPC Elements
Publisher: ASCE
Abstract: Exceptional mechanical properties of ultra-high performance concretes (UHPC) offer strong strengthening capacities in bending and shear when used as overlay on normal strength concrete (NSC) structures. Nonetheless, lack ...
Analytical Model for Calculating Shear Capacity of NSC Beams Strengthened by UHPC Lateral Layers
Publisher: ASCE
Abstract: The utilization of ultrahigh-performance concrete (UHPC) as lateral or U-shaped thin layers to strengthen the shear-deficient normal-strength concrete (NSC) beams is an effective and promising way to increase their stiffness ...
A Two-Dimensional Model of a Double-Façade With Integrated Photovoltaic Panels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Building integrated photovoltaic (PV) systems that include heat capture are more cost effective than PV systems that generate only electricity. This paper presents a two-dimensional control-volume ...
Experimental Investigation of the Shear Resistance Mechanism on Hybrid NSC-UHPC Predamaged and Undamaged Unidirectional Bridge Slabs
Publisher: ASCE
Abstract: This paper investigates the shear behavior of unidirectional hybrid slabs made of a normal-strength concrete (NSC) substrate and an ultrahigh-performance concrete (UHPC) overlay on the tensile side. The impacts of two ...
3D Nonlinear Finite-Element Modeling of Lap Splices in UHPFRC
Publisher: American Society of Civil Engineers
Abstract: Development in ultra-high-performance fiber-reinforced concrete (UHPFRC) structural applications that has taken place over the last two decades has generated innovative concepts that could significantly impact the concrete ...
Structural Behavior of Bridge Decks with Cast-in-Place and Precast Concrete Barriers: Numerical Modeling
Publisher: American Society of Civil Engineers
Abstract: Nonlinear finite-element (NLFE) calculations were used to compare and optimize the load transfer and failure mode of precast and cast-in-place bridge barriers subjected to transverse loads on bridge deck overhangs. The ...
Static and Dynamic Behavior of High- and Ultrahigh-Performance Fiber-Reinforced Concrete Precast Bridge Parapets
Publisher: American Society of Civil Engineers
Abstract: New designs of precast bridge parapets made with fiber-reinforced concrete (FRC) were developed using nonlinear finite-element calculations. Specific properties of high- and ultrahigh-performance FRC were exploited in these ...
