Thirteen 8-ft by 8-ft shear panels and fifteen 16-in by 18-in shear panels were tested dynamically at the Structural Testing Laboratory, Richmond Field Station, University of California,...
Current Research and Future Developments
A review of current research projects at the National Science Foundation on bridge engineering are reviewed and discussed with respect to immediate and future impacts. A look into the...
Overview of Programs at Sandia National Laboratories
This paper presents on overview of the containment integrity programs at Sandia National Laboratories. Companion papers at this conference give greater details about the construction,...
Fourier Series Expansion on Determination of Response Bound of Beam
Fourier series expansion is suggested to discrete the continuous vibrating system by regarding Fourier constants as generalized displacement parameters. The orthogonal merit to the terms...
Aerodynamic Modeling of Chimneys
The wake induced acrosswind behavior of circular cross-section structures, such as industrial chimney, has been studied for many years using wind tunnel models. Due to the relaxation of...
Mitigation of Wind-Induced Vibration of Tall Buildings
This paper summarizes a detailed study of the sensitivity of building acceleration to changes in structural stiffness, mass and damping and to the eccentricities in the centers of stiffness...
Aerodynamic Methods for Mitigating Wind-Induced Building Motions
Excessive wind-induced motions of tall buildings most frequently result from vortex shedding induced across-wind oscillations. This form of excitation is most pronounced for relatively...
Floor Response Spectra Including Structure-Equipment Interaction Effects
An efficient method for generating floor response spectra with the structure-equipment interaction effects is proposed. Floor response spectra are computed from a prescribed ground response...
A New Proposal of Design Wind Loads for Beams Supporting Long-Span Roofs
The wind tunnel testings of wind pressures acting on long-span roofs are carried out. Dynamic wind pressures are measured simultaneously at a lot of points on the roofs. The instantaneous...
Safety Evaluation and Verification by Field Testing of Concrete Bridges
This paper describes a method of safety evaluation of concrete bridges in service and the verification of the evaluated results by field tests. The field tests to evaluate structural safety...
Seismic Design of Cable-Stayed Bridges: Evaluation and Research Needs
Earthquake-response characteristics of cable-stayed bridge are evaluated. 2-D and 3-D models are considered. The cases of multiple-support and uniform excitations are considered; furthermore,...
Impact of Errors on Safety During Construction
The construction process involves a number of procedures which integrate together from the first intention of building the project to the end of the structural cycle. In this study, a...
Instrumentation of the Shenyang T.V. Tower
The recently-completed Shenyang radio and television tower provides a unique opportunity to obtain comprehensive measurements of the along-span variation and coherence of wind-induced...
Analysis of Glulam Lattice Dome
Glued-laminated timber (glulam) domes have become competitive in the engineering of large-span roof structures. Three-way glulam grid domes, such as the Triax and Varax domes, are particularly...
On the Analysis of Viscoelastic Plane Frames
Since its foundation on 1986 the Computational Mechanics Laboratory at the Polytechnic School of Sao Paulo has often been asked for non-linear stability analysis of wood and concrete structures....
In-Plane Behavior of Concrete Masonry Coupled Walls
To study the in-plane seismic resistance of multi-story masonry coupled walls, 6 full-scale reinforced masonry specimens, each two stories high, are being constructed and tested in the...
Influence of Nonlinear Models on Dynamic Displacements
This research is a part of an ongoing multi-year program that is sponsored by the National Science Foundation and conducted under the TCCMAR (Technical Coordinating Committee for Masonry...
