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...

Inelastic Response of Buried Pipelines Due to Landslide Effects
During earthquakes, a buried pipeline may experience significant loading as a result of large relative displacements of the ground along its length. Large ground movements can be caused...

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...

Dynamic Response of a Building with Dual System
The paper presents the dynamic response of a 30-story building with dual system consisting of cross-bracing and beam-column moment resisting frames. Two types of beam-column connections,...

Tuned Liquid Damper and Its Application to Tower-Like Structures
A new kind of damper, Tuned Liquid Damper (TLD) relying upon motion of, shallow liquid in a rigid container for absorbing and dissipating the vibrations energy is explained. The performance...

Local Wind Pressures on Roofs
The paper reviews the results of the most recent research studies in the evaluation of wind pressure coefficients for the design of roof cladding elements. The effect of roof geometry...

Wind Effects on Loose-Laid Cladding Systems
Modern roofing systems for flat roofs frequently make use of rigid insulation boards, gravel and concrete pavers that are loose-laid on top of the waterproof membrane. The authors have...

Seismic Response of Multistory Building Structures With Flexible Floor Diaphragms
An efficient model for three-dimensional analysis of multistory structures with flexible floor diaphragms is proposed in this paper. Three-dimensional analysis of a building structure...

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...

Optimum RC Member Design With Discrete Sections

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,...

Some Design Considerations During Construction
Certain construction failures are discussed with associated design conditions leading to these failures. Some points of interest for engineers involved with construction equipment designs...

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...
