Behavior of Type 2 Steel Frames
In the design of steel building frames, various simplifying assumptions are usually introduced when determining member design forces. Typically, the beams are assumed to be either rigidly...

Experimental Study of Thin-Web Welded H Columns
Little attention has heretofore been paid to the strength of welded thin-web columns. The purpose of this research was to determine what factors affected the strength of this type of column....

Structural Analysis of Wood Floor Systems
A combined Fourier series and finite element analysis of wood floors is presented, and its implementation in a computer with small core memory is discussed. Predictions using the model...

Safety Checking Formats for Limit States Design
The growing need for a unified approach to structural design for different construction materials and technologies is met by the limit states design approach. Several standards-writing...

Thermal Convection and Design Wind Speeds
This technical note presents estimates of the extent to which thermal convection effects cause mean wind profiles to deviate from the logarithmic law. It is shown that the deviations from...

Multiple Column Curves by Modifying Factors
There are two principal disadvantages in the use of multiple column curves as they are currently formulated. First, they are represented either by equations which are cumbersome to use...

Method of Imaginary Reactions for Taut Cables
The problem of determining the three dimensional equilibrium shape of an arbitrarily loaded cable is a classical one in nonlinear structural mechanics. This note presents a new technique,...

Vibrations of Inclined Slack Cables
Three previously reported experiments on vibrations of inclined slack cables are examined. It is stated that a linear theory is a valuable tool in the analysis of marine cable vibrations...

Lateral Buckling Tests on Welded Continuous Beams
Twenty-one two-span continuous beams with nominally identical cross sections of welded I-250x100x6x8 mm are tested in seven groups of three, each group having different span length. These...

Inelastic Cyclic Analysis of Pinned-Ended Tubes
An analytical study of the inelastic cyclic load-deflection behavior and load-shortening behavior of axially loaded steel tubular bracing members subject to cyclic loading is presented....

Full-Scale Tests on Single-Tapered Glulam Members
Analytical and experimental studies were conducted on Glulam members with tapered configuration. Full-scale flexural tests were conducted under working loads. Three different geometries...

Full-Scale Tests on Double-Tapered Glulam Beams
Analytical and experimental studies were performed on straight-soffited, double-tapered glulam beams. Full-scale tests were conducted under working loads to evaluate the applicabiLity...

Ultimate Strength of Biaxially Loaded Composite Sections
A theory is developed for the non-linear or linear analysis of arbitrary composite sections subjected to biaxial loading. The accuracy of the theory is verified by comparison with known...

Rigidities of Nonorthogonally Shaped Waffle Slabs
Theoretical formulae are presented for the various rigidities of non-orthogonally shaped waffle concrete slabs for both the precracking and postcracking stages. The deduced expressions...

Creep of Concrete in Variable Environments
Creep and shrinkage measurements are reported on three steam-cured and one moist-cured control concrete. Half the specimens were stored in a constant environment of 70° F and 50% RH, and...

Internal Pressure and Building Safety
The wind-induced pressure inside buildings has a profound effect on building safety. Yet, little attention has been given to it in the past. The effect is either ignored or improperly...

Mutual Interference Drag on Signs and Luminaires
Wind tunnel tests were conducted to determine the increase in drag on flat plate and luminaire models due to the proximity of nearby models of like shape. Test results showed drag increases...

Eccentric Bracing in Tall Buildings
Primary concerns in the design of high-rise buildings, particularly those located in seismically active regions, are the control of interstory drift and the ability of the structure to...

Finite Element Analysis of RHS T-Joints
The finite element method (FEM) is used to model the behavior of rectangular hollow section (RHS) T-joints beyond the elastic limit, and is applied to determine their ultimate and working...

Elastic Buckling of Laterally Continuous I-Beams
An approximate method for determining the elastic flexural-torsional buckling loads of laterally continuous structures is developed. The method can be applied to structures loaded at braced...
