Development of Hardwood Glulam Timber Bridge Standards
Design standards and specification for 5.5 to 27.4 m(18 to 90 ft.) clear span hardwood glued laminated (glulam) highway bridges have been developed and are available from the Pennsylvania...

Design and Field Performance of a Metal-Plate-Connected Wood Truss Bridge
This paper describes an on-going study on the design and performance attributes of an experimental wood-truss bridge. This is believed to be the first roadway bridge application of metal-plate-connected...

Bulb-T and Glulam-FRP Beams for Timber Bridges
In this paper, we discusses the manufacturing, analysis, and testing of two glulam beam designers:(1) Southern pine bulb, and (2) yellow-poplar reinforced with pultruded fiber-reinforced...

LRFD vs. ASD for Wood Structures
There is a growing preference within the structural engineering community for the adoption of reliability-based load and resistance factor design (LRFD) procedures in lieu of traditional...

What Controls the Ultimate Load of a Glulam Dome?
A glulam dome is analyzed with the finite element method to determine the governing failure mode and ultimate snow loads. The dome consists of a triangulated network of curved glulam beams,...

Timber Structures
This paper deals with three different curvilinear timber structures of moderate spans - 120 feet to 200 fee +/-. In each of the three cases cited, the roof deck and boundary members are...

Experimental Study on a Buckling Behavior of a Wooden Single-Layer Space Frame of Reticular Shell on a Hexagonal Plan: Influence due to the Bolted Joint Looseness with Axial and Bending Resistance
The authors have investigated about the structural behavior of a wooden single-layer space frame structure with the bolted joints. We have carried out a buckling tests of a wooden single-layer...

Design and Construction of the Cable-Stayed Wooden Space Truss Roof
The thinning must be enforced for healthy development of an artificial forest. The most effective use of thinning lumber is construct of the space truss structure. This election systems...

Architecture and Lightweight Structures: A Methodical Design Approach
Lightweight structures such as membrane structures, shells, space-grid, lightweight trussed and suspended structures have become an integral part of the international building scene. While...

Representing Design Cases Based on Methods
This paper discusses an approach to representing design cases using the methods used in solving specific design problems. This differs from the conventional representation of design cases...

A program for the Analysis of Pile Load Tests
The load capacity of piles are routinely determined from full scale pile load tests under actual field conditions. Several empirical methods were proposed for the analysis of field load/settlement...

Estimating Sediment Relative Density Using an Impact Core Sampler and Wave Equation-based Pile Analysis
This paper presents a case history in which soil sample drive resistance was modeled with a wave equation-based pile analysis computer program to estimate in situ sediment relative densities...

Computer Analysis of Lateral Loading in Wood-Framed Structures
Building codes and design techniques associated with single-family housing need to incorporate advances in architecture and construction so that the traditional life-safety building codes...

Methods to Reduce the Settlement of Embankments on Soft Clay: A Review
New trends have been observed during the past ten years in the practice of settlement control for embankments on soft clays: they include increased use of rigid (piles) or semi-rigid (stone...

Deformations in Sand Layer During Pile Driving
This paper presents measurements of settlement and lateral soil movements in a medium dense to dense sand layer due to densification during driving of precast concrete piles. At one end...

Pile Settlement Based on Dynamic Measurements
Dynamic measurements during driving are well established for monitoring driving performance and the prediction of pile capacity. Post driving, signal matching office methods (e.g. CAPWAP)...

Static Pile Load-Movement From Dynamic Measurements
Static loading tests have traditionally been performed to determine the characteristics of pile load-movement relationships. Due to the expense involved and time required, this type of...

Numerical Study of Underpinning by Piles for Settlement Control of Strip Foundations
A numerical study has been carried out of a simple idealized problem of a shallow strip foundation (both flexible and rigid) on clay underpinned by rows of piles. The work is directed...

Design and Performance of a Piled Raft Foundation
The foundation system for a recently constructed building in Perth, Western Australia, consisted of combined pile groups and raft elements, with a total of 280 bored piles incorporated...

Displacement of Batter Piles in Layered Soil
The displacements of flexible vertical and batter model piles under eccentric and inclined loads in layered soil of clay overlying sand is studied. Horizontal and vertical displacements...
