Tuned Mass Dampers for Towers and Buildings
Tuned mass dampers (TMD's) are used to reduce the response of tall slender structures to resonant wind-induced oscillations. This paper reviews the authors' experience with the design...
Wind-Induced Vibrations of Tall Buildings Using Tuned Mass Damper
A Lagrange formulation is applied to tall buildings using tuned mass damper. The resulting equations of motion are analyzed using a frequency window method. The method reduces the computational...
A Shear Transfer Model for Floor-To-Wall Connections in Concrete Masonry Structures
Based upon experiments conducted at the Univ of California, San Diego (UCSD) on floor-to-wall connections in concrete masonry structures, a constitutive model was developed for the overall...
Behavior and Design of Angle Connections Subjected to Cyclic Axial Force and Shear
The objectives of this study were to establish cyclic behavior of double angle shear connections subjected to axial load and to develop design recommendations. Five cyclic tests of double...
Interaction Between Beam and Steel Connections
The overall objective of the investigation is to study the behavior of a particular steel connection type, flush end plate steel connections, subjected to shear, axial forces, and possibly...
The Effect of Nonlinear Drag PSD on Fatigue of Compliant Offshore Structures
Structural fatigue damage induced by random ocean wave loading on a compliant type of offshore structure is considered. The nonlinear wave force is modeled by the Morison equation and...
The Innovative Concept of Semi-rigid Composite Beam
This paper discusses invention and development of a new type of composite beam called 'Semi-rigid Composite Beam.' This new type of beam is expected to behave better than presently used...
Field Measurements of Wind-Induced Pressures on Roofs of Low Buildings
Full-scale measurements have been carried out on an experimental building, 3.3 m high, beside the football field at the Loyola campus of Concordia University. Wind-induced pressures have...
Barriers for Innovation and Technology Transfer in the Public Works Infrastructure R&D
Utilization of technologies and innovation to revitalize America's public works infrastructure is beset with barriers. Some critical barriers, identified through literature review and...
The Dredging Research Program of the US Army Corps of Engineers
The Corps of Engineers Dredging Research Program (DRP) was established in Fiscal Year 1988 as a seven-year program with the objective of developing products that reduce the cost of dredging...
Management of San Diego Bay Dredged Material Disposal
This paper will discuss the Navy's efforts in the development and analysis of dredged material disposal from Navy projects within San Diego Bay. The impacts and mitigation for the alternatives...
Wave Climate Studies Along the Turkish Coast of the Black Sea
Wind-generated waves produce the most powerful forces to which coastal structures are subjected. Therefore, wave information is required for the proper planning and reliable design of...
Development of the Long Caisson Type Vertical Breakwater
The width of the caisson of a breakwater is calculated based mainly on the wave force expected to act on the caisson. IN this calculation, the assumed wave force is the peak wave force...
Determination of Hydraulic Roughness for Concrete-Lined, Supercritical Channels
A channel verification program has been initiated by the US Army Engineer District, Los Angeles to determine the hydraulic roughness of flow in a concrete channel. Specifically, this study...
Proposal on Story Drift Limit Based on Axial Behavior of Column under Seismic Loads
The main function of columns primarily is to support axial loads both under and after repeated lateral loading from earthquakes. A definition of the story drift limit in any structural...
Strength Deterioration Behavior of Concrete-Filled Steel Tubular Beam-Columns
Cantilever beam-columns of steel square hollow section with or without filled-concrete were tested under constant axial load and alternately repeated horizontal load to investigate the...
SHRP Deformation Test?Asphalt Mix Tests and Analysis Systems
From analyses of existing information on the permanent-deformation characteristics of asphalt/binder-aggregate mixes, as well as the development of permanent deformation in pavement structures,...
Seismic Design of Multi-Story, Wood-Framed Buildings
The seismic design and analysis of wood-framed structures is relatively simple; however, the challenges that present themselves within this design medium are shear and overturning force...
Evaluation of Dilatometer Method to Determine Axial Capacity of Driven Model Pipe Piles in Clay
The flat Dilatometer (DMT) provides a unique approach to estimate the effective stress axial capacity of driven displacement piles in clay. An investigation using this approach was performed...
3-D Deformation Analysis of Pile Groups During Wave Loading
Deformation predictions of pile group supporting one leg of Magnus platform were conducted using the 3-D nonlinear computer program SPLICE (Structure/Pile/Soil Interaction Analysis) and...
