Sheet Steel Welding
Light, cold formed steel sections have been arc welded without the benefit of a general guiding specification for many years. By the late 1960's the structural use of the...

Determination of Track Gage Widening Parameters

Simplified Design of Corrugated Shear Diaphragms
Closed form expressions for the flexibility and fastener forces are developed for metal corrugated shear diaphragms. The formulas are applicable to both direct and indirect shear transfer...

Nonlinear Layered Timber Cylindrical Shells
The finite element method was used to model and analyze two cylindrical shells—one nail fastened and one glued—taking into account geometric and material nonlinearities. Earlier tests...

Stability of Discretely Fastened Plates

Design Formulas for Steel Folded Plate Roofs
Formulas are presented for the design of folded plate roofs using profiled steel sheeting and standard fastenings, based on their known performance in shear. As a result of full-scale...

Empire State: Greatest of All Skyscrapers
The Empire State Building! That major name instantly brings to mind Manhattan's intoxicating skyline, a skyline this greatest of all skyscrapers has dominated for 45 years....

Empire State: Greatest of All Skyscrapers
The Empire State Building! That major name instantly brings to mind Manhattan's intoxicating skyline, a skyline this greatest of all skyscrapers has dominated for 45 years....

Stiffness Center Method
A approximate analysis of rigid frames using a new concept, called the stiffness center, is presented. It has been shown that when a skeletal elastic system is idealized as a configuration...

Survey of Research on Structural Connections
The Task Committee on Structural Connections decided to survey the current state of research and research needs in the general area of structural connections in metal. The information...

Behavior and Design of Shingle Joints
Seven shingle joints of A572 steel were fastened with 7/8-inc. (22.3-mm) A325 bolts; the remaining 2 joints were fastened with 7/8-in. (22.3-mm) Huckbolts. The variables covered in this...

Eccentrically Loaded Bolted Connections
Although present methods of investigating eccentrically loaded fastener groups have produced safe designs, the factor of safety is, in general, unknown. A rational theoretical method of...

Resilient Ferry Slip with Retractable Fender
The design of a ferry slip using retractable contact frames, moving inward and upward on bearing brackets with tracks of various inclination is described. The rigid frame on which the...

A514 Steel Joints Fastened by A490 Bolts
Results are reported of analytical and experimental studies of the behavior of construction alloy (ASH) butt splices which use A490 fasteners. Based on the results of previous theoretical...

Shear Flexibility and Strength of Corrugated Decks
A brief review is made of the mainly experimental work which has been carried out on shear diaphragms. To make full use of the shear properties of steel decks, it is desirable to be able...

AITC Timber Construction Manual
The purpose, development, and contents of the Timber Construction Manual, prepared by the American Institute of Timber Construction, are evaluated. The First Edition of the Timber Construction...

Bearing-Type Bolted Hybrid Joints
The results of an analytical study of hybrid steel bolted joints of A36, A440, and A514 steel are presented. The joints were fastened by either A325 or A490 bolts. The studies were designed...

A440 Steel Joints Connected by A490 Bolts
The results of tests conducted to determine the behavior of joints fabricated of A440 steel plate and fastened with 7/8-in. diameter ASTM A490 bolts are covered in this report. The experimental...

Structural Action of Pile Cluster Dolphins
Dolphins were investigated for the three cases in which (1) piles are rigidly fastened at their heads; (2) shear flexibility is permitted between piles; and (3) plastic yield is permitted...

Criteria for Designing Bearing-Type Bolted Joints
The current (1965) criteria for proportioning bearing-type bolted joints are reviewed. The concepts of balanced design are examined and existing test results of bolted A7 and A440 steel...
