Natural Decay Resistance of Glued-Laminated Beams
The natural decay resistance of untreated Douglas-fir heartwood specimens sampled from glued-laminated beams was evaluated using a modified agar plate test modeled after the European Standard...

The Challenge of Housing the Largest Detector
The most innovative part of the structural-civil design of the Superconducting Super Collider (SSC) is that of the underground experimental halls located alongside the 86 kilometer collider...

High Strength Shotcrete and Concrete on the SSC Project
This paper addresses the technical aspects related to the use of high strength shotcrete and concrete on the Superconducting Super Collider (SSC) project. 7,000 psi shotcrete and 8,000...

Steel-Concrete Interaction by Means of Film Sensors
By adapting a recently-developed technique based on the piezoelectrical properties of relatively thick films made of Polyvinyldifluor organic composites and extensively used in robotics,...

Shear Design Guidelines for Polyester Concrete Using Recycled Plastic
Previous research on the shear behavior of steel-reinforced polymer concrete (PC) beams has been very limited and no efficient design procedures have been proposed. In all the previous...

Dynamic Response of Steel Fiber Reinforced Concrete
Extensive research has been done on the static properties of steel fiber reinforced concrete, but very little on the dynamic properties. A total of 20 beams was tested. The steel fiber...

Characterization of an ER Active Member
In the presence of strong electric fields (kV/mm), electrorheological (ER) materials change form viscous fluids to yielding materials. The class of ER materials used in this study have...

Control of Random Crack Formation in Portland Cement Concrete Pavements
Random crack formation in concrete pavements, which is mainly due to the development of tensile stress caused by temperature-induced volumetric change and shrinkage deformation at early...

Synopsis of a Manual on Structural Fire Protection
Structural Fire Protection : Manual of Practice was published in 1992 by the American Society of Civil Engineers. The Manual has two major parts. Part I (Chapters 1 to 3) introduces the...

Design and Analysis of the 712 Fifth Avenue Structure
New York City's 712 Fifth Avenue is an extremely-slender concrete tube tower. This text addresses the structure's lateral structural system, wind analysis, computer model, thermal analysis...

AWS versus AIJ Tubular K-Connection Design Rules
Among various existing design rules for circular tubular connections, the AWS rules are compared with the AIJ rules because of differences between the two. Subjects of discussion include...

The Behaviour and Design of Stressed-Arch (Strarch) Frames
The paper presents an overview of the stressed-arch structural system and the associated research program undertaken at the University of Sydney between 1988 and 1992. The objectives of...

Spherical Domes Subjected to Horizontal Earthquakes
The purpose of this paper is to get a powerful tool for response analysis of a spherical dome subjected to dynamic excitation based on mathematical analytic method, i.e., the Galerkin...

Continuous Pulse Control of Structures with Material Nonlinearity
A control method is presented for reducing the dynamic response of structures in the inelastic material range using a control force from an active control system. The proposed method of...

Imperfections and Thin-Walled Bars Behaviour
Experimental and theoretical observations allowed us to present some new conclusions concerning the proper, and safe designing of the structures composed of thin-walled bars (TWB). These...

Large Deformation Analysis of Lattice Truss Structures Including Hysteretic Material Behavior
A methodology is presented to analyze lattice truss structures including both material and geometric nonlinearities. Modeled member material behavior modes include: buckling, yielding,...

Ultimate Loading Capacity of Braced Domes
The stability behaviors of a practical latticed dome with 40 metres span are studied in this paper. The geometric and material nonlinear behaviors, as well as the effects of the initial...

The Use of ETFE Foils in Lightweight Roof Constructions
ETFE foils are polymer film sheets which are enclosed in support frames and inflated to provide stable, insulated and transparent roof cushions for lightweight enclosures. This paper describes...

Study on Mechanical Characteristics of Light-weight Complex Structure Composed of a Membrane and a Beam String Structure
This paper aims at studying a new type of Beam String Structure, in which a membrane is used as finishing material. This paper reports on the mechanical characteristics of this structure,...

A Shape-Finding Finite Element Analysis for an Equally-Stressed Surface in Membrane Structures
A finite element method is proposed to obtain an equally-stressed surface in a membrane structure, where the displacements and rotations of a membrane are in general finite and nonlinear....
