Reliability of Aluminum Beam-Columns
A review of reliability computation methods is presented. The strength of aluminum beam-columns is described, taking into account material and cross-sectional properties, initial imperfection...

Optimal Design Based on Approximate Scaling
A new optimal design procedure, intended to reduce the number of exact analyses during the solution process, is proposed. High quality explicit approximations of the structural behaviour...

Bayesian Approach to Prototype Testing
The strength of series-produced structures is uncertain because of modelling error and material parameter uncertainty. By testing of prototypes, information on both uncertainties is obtained....

Effect of Abandoned Roles on Capacity of Wedge Bolts
Seventy, 5/8-in. diameter wedge anchors were tested in direct pull-out to determine the effect of various configurations of unused holes and different treatments of these holes on pull-out...

Load Capacity of Concrete Bridge Decks
The behavior of two reduced-scale concrete bridge decks subjected to simulated wheel loads was evaluated in a series of tests. One slab was reinforced in accordance with AASHTO requirements;...

Concrete Members Under Combined Torsion and Shear
The behaviour of reinforced concrete members subjected to combined torsion and shear is studied in this investigation. An analysis is developed for predicting the deformations at all levels...

A Shear Lag Anomaly
This technical note reports an interesting phenomenon associated with shear lag in the flanges of box girders that is quite contrary to well established ideas concerning this subject....

Limit Analysis without Mechanism Generation
It is demonstrated that the static approach to collapse load analysis for frames can be implemented without mechanism generation and virtual work. In addition, the amount of programming...

Shearing Stress due to Prestress in Variable Depth Beam
General formulas to estimate shearing stress in prestressed concrete beams due to prestress force are given. These equations also can be used to calculate dead load and live load moment...

Probabilistic Description of Hurricane Wind Speeds
Information is presented on the parameters of the best fitting Weibull distribution estimated for simulated hurricane windspeeds. The effect of the assumption that an Extreme Type I distribution,...

2-D Finite Element Analysis of Massive RC Structures
Nonlinear analysis of concrete structures using finite elements is discussed. The applications include a thick-walled top-closure for a pressure vessel as well as the delicate problems...

Lateral Stability of I-Beams with Partial Support
The lateral torsional buckling behavior of I beams with tension flange restraint is described. Tension flange restraint occurs frequently in continuous beams and indeterminate structures....

Optimum Design of Prestressed Concrete Tension Members
A systematic procedure is proposed for the design of prestressed concrete tensile members. The design criteria considered include maximum allowable compression, ultimate strength, safety...

Meridional Imperfection in Cooling Tower Design: Update
The effect of meridional imperfection in hyperbolic cooling towers is studied in a continuation of an earlier study by the writers; the present paper takes into account the parallel work...

Epoxy-Repaired Concrete Walls Under Fire Exposure
The strength properties and other important parameters regarding the behavior of epoxy repaired concrete walls during fire exposure are experimentally determined. Both ASTM E-119 and the...

Seismic Design of Steel Buildings
An approach for the ultimate limit state design of steel buildings against the credible severest earthquake is presented on the basis of energy concept. The safety of a structure is judged...

Prestressed Concrete Flexural Members: Design
An alternate method for the design of prestressed concrete flexural members using the service load criteria is presented. The method differs from other available methods, in the sense...

Load Redistribution of Cracked Girders
Design of many bridges is controlled by the fatigue requirements. Such control can be minimized if the classification from a non-redundant to redundant structure is selected. Such a classification...

Circularly Curved Beams under Plane Loads
The exact 6 x 6 stiffness matrix for a circularly curved beam subjected to loading in its own plane, derived from the governing differential equations and from the finite element procedure,...

Laterally Loaded Cylinders in Half Space
The extended Neuber solution which has the curl of a harmonic vector added to Papkovich-Neuber solution is proposed as a useful solution to asymmetric problems referring to cylindrical...
