Flexural Member Bending Strength Limits in the New LRFD Bridge Code
Unified Code Provisions for Concrete Bridges
Provisions on limiting the flexural reinforcement adopted in the new AASHTO LRFD Specification for Bridge Design are summarized (1). They address minimum and maximum levels of reinforcement...
Effects of Site Conditions of Earthquake-Resistant Design of Structures
After a brief discussion of the importance of reliable establishment of design Earthquake Ground Motions (EQGMs) for efficient Earthquake-Resistant Design (EQ-RD) of structures, this paper...
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...
A Self-Balancing Laminate
A self balancing wood laminate has been developed based on the principle of orthotropic elasticity. Lumber is cut into three sections in the flatwise plane and each side member is turned...
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...
Externally Stiffened I-Beam to Box-Column Connections
This paper is concerned with I-beam to Box-column connections stiffened externally. Experimental and theoretical findings on full-scale connection models are highlighted. The performance...
Seismic Strengthening of URM Buildings with Steel Bracing
Unreinforced masonry (URM) buildings with large open fronts are extremely vulnerable to seismic inputs posing serious life safety hazard. Steel bracing systems have been used to upgrade...
Biaxial Testing of Brittle Repair Material for Rigid Pavements
Most codes of practice prescribe procedures for selecting patch configuration and material based on test devised for evaluating new pavement materials. This study is aimed at examined...
Cyclical Behavior of Welded Steel Shear Studs
Four specimens of composite steel and concrete beams were experimentally tested to obtain the cyclical behavior of the welded steel shear stud. This information may be used for the analysis...
Rigid Beam-To-Column Connection Detail for Circular Composite Columns
Steel pipes with relatively thin wall thickness and filled with high strength concrete have been used in building construction. Some of the advantages of this type of column include eliminating...
A Shear-Flexure Model for Non-Ductile Reinforced Concrete Bridge Columns under Biaxial Seismic Loading
In-Place Determination of Concrete Strength by the Impact-Echo Method
A Generalized Approach to the Local Stability of Stiffened Plates: Part I–Mathematical Formulation
The paper describes a generalized approach for the determination of the buckling stress of stiffened plates under combination of uniform biaxial compression, in-plane bending and shear...
Design of Half-Through or Pony Truss Bridges Using Square or Rectangular Hollow Structural Sections
The initial part of this paper will outline some of the research, testing, and investigation which has been done on half-through truss bridges. This research is primarily concerned with...
Research of Strength and Deformations with Long-time Loading and the Use of Glassfiber Reinforced Concrete in Shells
Presented is an experimental research on the properties of behavior on compression and tension of glassfiber reinforced concrete of alkali-resistant glass fiber under long-time load and...
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...
Experimental Study on the Buckling Behavior of a Triodetic Aluminum Space Frame: No. 2 Ultimate Bearing Strength of a Single Layer Space Frame
Membrane Structures: Technological Innovation and Architectural Opportunity
Presented is a list of materials used in building an airhouse. There are so many other moves in tensile structures and the present interest is in ETFE foils because of light transmission/cost...
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...
