Stable Pde Solution Methods For Large Multiquadric Shape Parameters, Nicolas Ali Libre, Arezoo Emdadi, Edward J. Kansa, Mohammad Rahimian, Mohammad Shekarchi

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

We present a new method based upon the paper of Volokh and Vilney (2000) that produces highly accurate and stable solutions to very ill-conditioned multiquadric (MQ) radial basis function (RBF) asymmetric collocation methods for partial differential equations (PDEs). We demonstrate that the modified Volokh-Vilney algorithm that we name the improved truncated singular value decomposition (IT-SVD) produces highly accurate and stable numerical solutions for large values of a constant MQ shape parameter, c, that exceeds the critical value of c based upon Gaussian elimination.

A Stabilized Rbf Collocation Scheme For Neumann Type Boundary Value Problems, Nicolas Ali Libre, Arezoo Emdadi, Edward J. Kansa, Mohammad Rahimian, Mohammad Shekarchi

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The numerical solution of partial differential equations (PDEs) with Neumann boundary conditions (BCs) resulted from strong form collocation scheme are typically much poorer in accuracy compared to those with pure Dirichlet BCs. In this paper, we show numerically that the reason of the reduced accuracy is that Neumann BC requires the approximation of the spatial derivatives at Neumann boundaries which are significantly less accurate than approximation of main function. Therefore, we utilize boundary treatment schemes that based upon increasing the accuracy of spatial derivatives at boundaries. Increased accuracy of the spatial derivative approximation can be achieved by h-refmement reducing the …

Steel Sheet Sheathing Options For Cfs Framed Shear Wall Assemblies Providing Shear Resistance, Cheng Yu, Hitesh Vora, Tony Dainard, Jimmy Tucker, Pradeep Veetvkuri

American Iron and Steel Institute (AISI) Specifications, Standards, Manuals and Research Reports (1946 - present)

The North American Standard for Cold-Formed Steel Framing - Lateral Design, AISI S213-07, provides design provisions for cold-formed steel framed shear walls with steel sheet sheathing. However, options are limited to 18-mil and 27-mil steel sheet sheathing. Presented in this report are the findings from an extensive monotonic and cyclic testing program conducted at the University of North Texas of 30-mil and 33-mil steel sheet sheathed shear walls with 2:1 and 4:1 aspect ratios and 27-mil sheet steel shear walls with 2:1 aspect ratio and 6-in., 4-in., 3-in., and 2-in. fastener spacing at panel edges.

Steel Sheet Sheathing Options For Cfs Framed Shear Wall Aseemblies Providing Shear Resistance, Cheng Yu, Hitesh Vora, Tony Dainard, Pradeep Veetvkuri

CCFSS Library (1939 - present)

In cold-formed steel construction, stud walls covered with steel sheet sheathing is an available option to resist lateral loads such as those caused by wind and earthquakes. The current American Iron and Steel Institute (AISI) Standard for Cold-Formed Steel Framing - Lateral Design 2004 Edition provides nominal shear strength for a limited range of steel sheet sheathed shear wall configurations. This report presents a research project developed to add values for 0.030-in. and 0.033-in. steel sheet sheathed shear walls with 2:1 and 4:1 aspect ratios and 0.027-in. sheet steel shear walls with 2:1 aspect ratio and 6-in., 4-in., 3-in., and …

Assessment Of The Bill Emerson Memorial Cable-Stayed Bridge Based On Seismic Instrumentation Data, Genda Chen, Dongming Yan, Wenjian Wang, Man Zheng, Louis Ge, Frank Liu

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

In this study, both ambient and earthquake data measured from the Bill Emerson Memorial Cable-stayed Bridge are reported and analyzed. Based on the seismic instrumentation data, the vibration characteristics of the bridge are investigated and used to validate a three-dimensional Finite Element (3-D FE) model of the bridge structure. The 3-D model is rigorous and comprehensive, representing realistic dynamic behaviors of the bridge. It takes into account the geometric nonlinear properties caused by cable sagging and soil-foundation-structure interaction in the Illinois approach of the bridge. The FE model is successfully verified and validated by using the natural frequencies and mode …

This report presents the results of 16 monotonic and 28 cyclic tests of flat strap X-braced walls, steel sheathed shear walls, high aspect ratio shear walls and shear walls framed with 54-mil and 43-mil studs. The findings provided a basis for continued research and development efforts, leading to the establishment of provisions for cold-formed steel-framed diagonal strap braced walls and Type I shear walls.

Nondestructive Evaluation Of Rc Structures Strengthened With Frp Laminates Containing Near-Surface Defects In The Form Of Delaminations, Mahmut Ekenel, John J. Myers

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Fiber reinforced polymer (FRP) composites are being utilized in a wide range of application areas in structural rehabilitations because these materials are less affected by corrosive environmental conditions and known to provide longer life with less maintenance. However, there are still some concerns about FRP strengthened reinforced concrete (RC) structures, such as the presence of near-surface defects. Currently limited data exists regarding this issue. the presence of near-surface defects in the form of delaminations between the fiber reinforced polymer (FRP) laminate and concrete substrate can significantly affect the structural integrity and stiffness of the structural section. These defects should be …

Testing And Evaluation Of Light Gauge Steel Frame / 9.5 Mm Csp Wood Panel Shear Walls, David Rokas

CCFSS Library (1939 - present)

The use of light gauge steel framing elements sheathed with wood plywood or oriented strand board are becoming more common in the construction of structural shear walls for low-rise platform frame structural systems in Canada. Canadian standards and codes do not currently outline design methods for this type of wall system. Therefore, research at McGill University is underway to help develop design parameters for seismic and wind loading that can be used in conjunction with the 2005 National Building Code of Canada for this type of shear wall system. The research is based on the monotonic and reversed cyclic testing …

Distortional Buckling Tests On Cold-Formed Steel Beams, Cheng Yu, Benjamin W. Schafer

CCFSS Proceedings of International Specialty Conference on Cold-Formed Steel Structures (1971 - 2018)

Laterally braced cold-formed steel beams generally fail due to local or distortional buckling. When the compression flange is not restrained by attachment to sheathing or paneling, such as in negative bending of continuous members (joist, purlins, etc.), members are prone to distortional failures. However, distortional buckling remains a largely unaddressed problem in the main body of the North American Specification (NAS 2001). Only a limited amount of experimental data on unrestricted distortional buckling in bending is available, therefore a new series of distortional buckling tests was completed. The test details are selected specifically to insure that distortional buckling is free …
