Structural Behavior Of Members Consisting Of Flat And Curved Elements, M. Brad Parks

Doctoral Dissertations

"Local buckling of stiffened and unstiffened curved elements has been investigated both experimentally and analytically. Stiffened curved elements are supported on all four edges while unstiffened curved elements are supported along three edges with one longitudinal edge free.

A series of stub column, beam, and shear tests have been performed for sections containing curved elements. The tested specimens were formed from sheet steels with yield strengths ranging from 27 to 88 ksi. The radius-to-thickness, R/t, values of the curved elements varied from 12 to 438 whereas the arc length-to-thickness, bit, ratios ranged from 23 to 218.

As a result of …

Elastic-Plastic Analysis Of Axisymmetrically Loaded Isotropic Circular And Annular Plates Undergoing Large Deflections, Aiman Raji Akileh

Dissertations and Theses

The concept of load analogy is used in the elastic and elastic-plastic analysis of isotropic circular and annular plates undergoing moderately large deflection. The effects of the nonlinear terms of lateral displacement and the plastic strains are considered as additional fictitious lateral loads, edge moments, and in-plane forces acting on the plate. The solution of an elastic or elastic-plastic Von Karman type plate is hence reduced to a set of two equivalent elastic plate problems with small displacements, namely, a plane problem in elasticity and a linear elastic plate bending problem. The method of finite element is employed to solve …

Experimental Study Of Rectangular Reinforced Concrete Members Under Combined Biaxial Bending And Tension, Naresh B. Patel

Theses

In practice it is a very common case to have a column subjected to combined effects of axial tension and biaxial bending moments and very few efforts are done to get good design approach for such special members.

So for this purpose, experiments were carried out on rectangular shapecolumns. Rectangular shaped columns were casted in homogeneous with brackets - one on each end and at connections haunches were provided to avoid the possible end failure. The overall shape of this configuration was "H" shape. Two hydraulic jacks were used; one on either side of the columns and thus column section …

Tests On Square Reinforced Concrete Members Under Combined Biaxial Bending And Tension, Bhadresh Shah

Theses

The research reported herein studies the ultimate strength behavior for square-shaped reinforced concrete short columns under combined biaxial bending and tension that is a common design problem. The present ACI building code (ACI 318-83) (1) and design hand book (2) do not offer an insight into the determination of strength and ductility behavior of biaxially loaded reinforced concrete columns. A design equation developed by Hsu (3,4,5 ) to study the ultimate strength behavior and failure surfaces for members under these combined action was used and the computed results were compared with the present analytical results and experimental results for square-shaped …

The Effect Of Grinding On The Sorption Capacity Of Activated Carbon, John Garrett Dempsey

Civil & Environmental Engineering Theses & Dissertations

The current procedure employed to design full scale activated carbon contacting systems is presented in detail and followed by a review of the more important process controls and operating parameters. Inherent limitations of the design procedure are identified, with the need to be able to accurately predict carbon sorption capacity from bench scale analysis determined to be the most important. Some of the more recent models developed to predict activated carbon sorption capacity were analyzed leading to the realization that even the most sophisticated dynamic models were based upon sorption capacities determined from classical isotherm procedures. The validity of the …

Analysis And Prediction Of The Water Temperature Of The Mckenzie River, Oregon Using The Equilibrium Temperature Approach, R. Peder Hansen

Dissertations and Theses

A one dimensional, steady flow, unsteady temperature model is used to evaluate the effects of two U.S. Army Corps of Engineers (COE) dams and resulting reservoirs on hourly water temperatures of the mainstem McKenzie River from Delta Park (RM 62.1) to Leaburg Dam (RM 38.8). Both COE projects are on tributaries to the McKenzie River and at present have only bottom withdrawl capabilities.

Water temperatures were simulated using the equilibrium temperature approach with air temperature used to estimate equilibrium temperature and also using computed hourly equilibrium temperature. Results obtained using computed equilibrium temperatures were less satisfactory than results using air …

Modelling Of Pile Load Tests In Weak Rock, Daniel Walter Caruso

Theses

The purpose of this thesis was to investigate the loss of load capacity of relaxed pile groups driven into weak bedrock. This was accomplished in the laboratory using a dynamic driving apparatus equipped with a static load testing system. The static load testing system applied loads hydraulically, and the load settlement behavior was monitored using an electronic load cell and a linear variable differential transducer (LVDT).

Tests were performed using 1" diameter steel pipe piles driven in a five pile group pattern at spacings of two diameters and four diameters. Piles were driven into a simulated rock mass consisting of …

Fracture Energy And Tensile Behavior Of Concrete, Wen-Jinn Chiou

Theses

Fracture behavior of concrete has been a subject of investigation for the past two decades. The need of understanding the complete tensile response of concrete is absolutely essential for theoretical modelling as well as design application of plain concrete structures.

In this study, attempts were made to investigate the validity of two important fracture parameters, namely, the fracture energy and the critical crack tip opening displacement. Three types of test specimen, dog- bone shaped tension specimen, notched beam and compact tension specimen, were investigated. These tests were conducted using the closed-loop MTS 810 strain-controlled testing system. For the uniaxial tension …

Study Of The Effects Of Pumping Pressure On The Properties Of Fresh Concrete, Dinesh Vithal Kenkre

Theses

This thesis has a two-fold objective. One, to develop a suitable testing apparatus in the labaratory to simulate the effect of field pumping of concrete and two, to conduct some preliminary tests to investigate the feasibility of the testing apparatus.

Pumping of concrete has been practiced in the U.S.A. since 1930. The behaviour of concrete in a pipeline has not been studied in much detail while development in the pumping technology raced ahead of the research in this field. Previous studies done in this field have clearly indicated the need for a laboratory simulation of pumping process in order that …

Pozzolanic Admixtures In Concrete Mix, Ronghao Chen

Theses

Fly ash and condensed silica fume are two main mineral pozzolanic admixtures in portland cement concrete. The increasing use of the fly ash in concrete projects and concrete products during the past 3O years and condensed silica fume in several projects during the past 1O years indicates a greater acceptance of them as the mineral pozzolanic admixtures in concrete. Although the engineers are of some identical views in using these industrial byproducts in concrete projects, there are different views on how the behavior and utilization of fly ash con-crete and condensed silica fume concrete since the byproducts are not the …

Effects Of Adhesion On The Active Pressure Exerted On A Retaining Wall, Thomas G. Gallagher

Theses

This paper investigated the effect of adhesion on the active pressure behind a retaining wall. No equation existed to solve for the active pressure for a sloped backfill that also takes into consideration cohesive and adhesive forces on a failure wedge. The trial—wedge solution(Culmann method) considers these parameters, but since it is a trial and error method it takes up too much time to solve. A shorter solution is desirable. An equation for the active pressure in terms of ρ(angle between horizontal and failure plane) was derived. A closed form solution for earth pressure was developed by setting the derivative …
