A weighted residual parabolic acceleration time integration method for problems in structural dynamics
(Walter de Gruyter GmbH, 2007)
In the proposed method, the variation of displacement in each time step
is assumed to be a fourth order polynomial in time and its five unknown coefficients are
calculated based on: two initial conditions from the previous ...
Comparison Of Distributed Versus Lumped Hydrologic Simulation Models Using Stationary And Moving Storm Events Applied To Small Synthetic Rectangular Basins And An Actual Watershed Basin
(Civil & Environmental Engineering, 2008-04-22)
The purpose of this investigation is to compare simulations using several artificial rectangular basins and a real drainage basin for distributed and lumped hydrologic models via results obtained with the U.S. Geological ...
General Response Of Kneading-compacted Unsaturated Silty Sand Under Drained And Undrained True Triaxial Testing
(Civil & Environmental Engineering, 2007-08-23)
A comprehensive series of 36 drained and 36 undrained true triaxial tests was accomplished to investigate the stress-strain-strength behaviour of kneading-compacted unsaturated silty sand (SP-SM) under multi-axial stress ...
Statistical Analysis Of Compressive Strength Of Clay Brick Masonry Prisms
(Civil & Environmental Engineering, 2007-08-23)
The Specification for Masonry Structures section of the current governing masonry design document in the U.S., reported by the Masonry Standards Joint Committee (MSJC), contains tables that can be used to determine the ...
Evaluation Of Texas Cone Penetrometer Test To Predict Undrained Shear Strength Of Clays
(Civil & Environmental Engineering, 2007-08-23)
The cone penetration test used in Texas is termed as Texas cone penetrometer (TCP), which works on dynamic principles similar to those of SPT, i.e. a hammer is used to drive the cone device for a preset depth of penetration ...
Building Pressure Tests Of Fiber-reinforced Foam-based Lightweight Concrete Precast Wall Panels
(Civil & Environmental Engineering, 2008-09-17)
Instrumentation and procedures for building pressure tests were designed as a
means of providing new wind pressure test methods for full-scale building models.
Fiber-reinforced foam-based lightweight concrete precast ...
Development Of Finite Element Method-based Model Equations For Hollow Tapered Poles
(Civil & Environmental Engineering, 2007-08-23)
This study presents the development of three-parameter load-deflection models for steel and FRP poles commonly used to support closed circuit television cameras. An experimental investigation is carried out to obtain static ...
Nonlinear Finite Element Model Analysis Of Human Accommodation Lens
(Civil & Environmental Engineering, 2007-08-23)
The crystalline human lens is modeled by using the finite element software, ABAQUS/CAE Version 6.5-1 as an axisymmetric shell to study the optical power and displacement of anterior and posterior poles induced due to zonule ...
Expressions For Bond Stress Of A Tension Splice In Steel Reinforced Concrete
(Civil & Environmental Engineering, 2007-08-23)
The aim of the research is to develop expressions for the bond stress at a tension splice in reinforced concrete. Many experiments have been conducted inorder to ascertain the relationship between appropriate variables and ...
Field And Experimental Studies To Assess The Performance of Stabilized Expansive Clay
(Civil & Environmental Engineering, 2007-08-23)
A vast majority of the expansive soils are montmorillonite-rich clays, over consolidated clays and shales. The swell and shrinkage movements of expansive soil cause considerable damage to structures such as buildings and ...
