Lower Bound Limit Design of Rectangular Slabs
A plastic method of design of rectangular slabs based on lower bound solutions of collapse has been developed. The slab is divided into middle and end zones so as to reinforce for beam...

Reliability Procedure for Fixed Offshore Platforms
This paper presents a method for calculating the notional risk of overload associated with fixed offshore platforms subjected to random wave loading. The lifetime exposure of the structure...

Composite Cold-Formed Steel-Concrete Beams
Experimental study was conducted at the University of Windsor and a composite beam system using soffits made of cold-formed steel channels was developed. The test results show good characteristics...

Analytical Model for Concrete Confinement in Tied Columns
An analytical model for the confinement mechanisms in tied columns has been developed. The model is based on the test results reported previously. A complete stress-strain curve for confined...

Tension Stiffening Concept Based on Bond Slip
Consideration of tension stiffening in reinforced concrete panels by means of so-called tension stiffening factors, appearing in total and incremental equilibrium equations, has proved...

Uniform Snow Loads on Structures
Data on ground and roof snow loads for 199 structures are analyzed. Relationships between ground-to-roof conversion factor for uniform roof loads and parameters such as roof slope, exposure...

Wind Pressures on Low Buildings with Parapets
The effect of parapets on the wind loading of low-rise buildings has been examined in the past, primarily under conditions of uniform flow not representing the variation of the mean speed...

Strengthening of Single-Span Steel-Beam Bridges
The use of post-tensioning to increase the strength of steel beams in beam and concrete-slab bridges is shown to be feasible. The purpose of the study is to determine a technique for increasing...

Assessment of Relaxation Loss Estimates for Strands
Significant variations in the techniques of measuring relaxation losses in prestressing strands and in the relaxation values recommended by the Australian and International Standards and...

Bolted Splice Connections with Undeveloped Fillers
The use of undeveloped filler plates has a definite influence on the loading and deformation behavior of bolted splice joints. Two replicate tests were completed on each of five different...

Serviceability Limit States: Connection Slip
The serviceability limit state for slip of bolted steel joints is the slip-resistance. The statistical properties of the parameters which define this resistance are presented and analyzed....

Composite Beams with Web Openings: Design
A general method for the analysis and design of composite steel-concrete beams with openings centered in the web of the steel section is developed. The approach is based on ultimate strength...

Method for Analysis for Guyed Towers
A method for static analysis of guyed towers is extended and applied to problems in three dimensions. The tower and guy cables may be loaded by arbitrary distributed or concentrated forces,...

Restrained Crooked Aluminum Columns
The strength of aluminum pinned crooked columns has been derived as the basis of a design column curve. The effective length factor concept has then been presented and a value for crooked...

Generalized Stiffness Matrix for Thin Walled Beams
Stiffness matrix for a structural member is obtained using the differential equations derived by V.Z. Vlasov. Presence of additional off-diagonal elements over the conventional tridiagonal...

Plastic Rotation of Composite Beams
The sagging rotation capacity of composite beams consisting of a concrete slab attached to a steel beam by a shear connection is studied. Tests are reported on four full-scale beams in...

Strength of Composite Beams at Web Openings
A model for the strength of steel-concrete composite beams with unreinforced, rectangular web openings is presented. The model includes the contribution of the concrete slab to shear strength,...

Acrosswind Response of Buildings
The acrosswind response of buildings is investigated. Expressions for the acrosswind loading are developed through the use of the spatio-temporal measurement of the fluctuating pressure...

Cooling Tower Shells Founded on Soil
A dynamic axisymmetric finite element model suitable for shells of revolution founded on ring footings is presented. The model consists of high-precision rotational shell finite elements,...

Application of Fracture Mechanics to Concrete Structures
Material properties (heterogeneity and non-linearity) and disturbing phenomena (slow crack growth and microcracking) cause several research-workers to be pessimistic about the applicability...
