Load Rate Effects on Concrete Compressive Strength
Plain concrete cylindrical specimens from six different concrete mixes, 51 mm in length and diameter, were tested in compression quasi-statically at strain rates between 10-6/sec...
Local Web Crippling of Unstiffened Multi-Cell Box Sections
Full-scale experiments and analyses show that the AISC/LRFD design equations for web yielding and web crippling strength of unstiffened webs, developed from test data on I sections, can...
Local Buckling of Pultruded FRP Beams: Theory and Experiment
A continuing experimental and theoretical investigation of the local compression flange buckling of commercially produced pultruded fiber-reinforced plastic (FRP) beams is briefly described...
Mechanical Behavior of Dowels Embedded in Concrete
In this paper an experimental investigation on the behavior of dowels embedded in concrete is described. The dowel strength under monotonic forces with two different boundary conditions...
The Effects of Bolt Over-Tightening on Bolted Connections
This paper describes a portion of the research program being conducted on structural connectors which have been over-tightened. Direct-Tension Indicators (DTI) may be specified for use...
Testing of Hollow Clay Tile Masonry Prisms
This paper presents test results of 610-mm wide (24-in.) by 1219-mm high (48-in) by 203- or 330-mm (8- or 13-in.) thick prisms constructed of hollow clay tiles. Three prisms were extracted...
Compressive Strength of Masonry Prisms
Many factors affect the estimation of compressive capacity of a masonry prism. In the study the effects due to grout strength, mortar joints, block geometry and size, moisture content,...
Towards Robust, Effective and Efficient Second Order Analysis of Practical Steel Frames
The performance of the widely used finite element and the stability function methods and the recently developed pointwise equilibrating element in second order nonlinear analysis of framed...
Nonlinear Analysis of Prestressed Concrete Structures
This paper presents a finite element model for the nonlinear analysis of prestressed concrete structures. The model can be used to analyze pretensioned or posttensioned, bonded or unbonded...
Impact of Non-Gaussian pdf on Reliability Estimates for Deep Water Platforms
The offshore community has invested a great deal in the analysis and design of compliant deep water platforms such as tension leg platforms (TLPs) and more recently spar platforms. Tension...
Compressive Strength of Large Scale HSLA-80 Steel Cellular Sections of a Double Hull Ship Structure
An analytical and experimental large scale test program was conducted to investigate the instability failure modes of cellular double hull box sections. The main emphasis of the study...
Some Aspects of Compression Member Design in Australia
The paper summarizes and elucidates the provisions of the Australian Standard AS4100-1990, Steel Structures, for the design of compression members. Emphasis is placed on those aspects...
Explorations in Geodesic Forms
Geodesic forms constitute an important family of structural systems. The objective of the paper is to show how the concepts of a mathematical tool called formex algebra and its programming...
Effect of Joint Rigidity on Buckling Strength of Single Layer Lattice Domes
The present paper discusses the effect of the joint rigidity on the buckling strength of single layer lattice domes, with regular three way grids, under vertical loading. The effect of...
Helium-Supported Hangar for a Small Solar-Powered Airship
For the IGA Expo '93 the Institute for Statics and Dynamics of Aerospace Structures, University of Stuttgart, together with Stuttgart Solar e.V. developed a solar-powered airship. For...
Effects of Spatial Triangulation on the Behavior of Tensegrity Domes
A number of long span 'tensegrity' dome type structures have recently been realized pursuant to the inventions of R. Buckminster Fuller and David H. Geiger. These structures have demonstrated...
A Practical Design and Construction of Tension Rod Supported Glazing
In designing a glass skin-covered space, for the atrium, entrance hall or other core part of a building complex, the high openness and quality requirements of the space often lead to the...
Form Finding Numerical Methods for Tensegrity Systems
The rigidification of Tensegrity Systems is related to selfstress states which can be achieved only when geometrical and mechanical requirements are simultaneously satisfied. This paper...
Expandable Structures with Incorporated Roofing Elements
In this paper design aspects of expandable structures with incorporated cover plates are studied. These roofing elements can be made by single plates or by self-folding plates. In both...
Spatial Structures Erected out of Thin Shell Elements Fabricated on Plane Followed by Bending
The paper offers the examples of spatial structures of average spans (up to 24 m) and engineering structures made of prefabricated curvilinear elements originally having a plane form....
