Effect Of Relative Density And Stress Level On The Bearing Capacity Of Footings On Sand, D Loukidis, Rodrigo Salgado

Lyles School of Civil Engineering Faculty Publications

The design of shallow foundations relies on bearing capacity values calculated using empirical procedures that are based in part on solutions obtained using the method of characteristics, which assumes a soil that is perfectly plastic following an associated flow rule. In this paper the problem of strip and circular footings resting on the surface of a sand layer is analysed using the finite-element method. Analyses are performed using a two-surface plasticity constitutive model that realistically captures the aspects of the mechanical response of sands that are relevant to the bearing capacity problem. In particular, the model accounts for non-associated flow, …

Fatigue Strength Of Steel Bridge Members With Intersecting Welds, David T. Delong, Mark D. Bowman

JTRP Technical Reports

The brittle fracture of the Hoan Bridge in December 2000 highlighted the fracture susceptibility of details containing intersecting welds in steel bridges. Though it is now known that details with intersecting welds should be avoided, many existing bridges in Indiana contain details with intersecting welds. Little experimental data on the fatigue performance of these details exists.

The purpose of this study was to evaluate the fatigue strength of several details commonly found in steel bridges in Indiana that contain intersecting welds. Large-scale experimental fatigue testing were performed using nine steel beams to study the behavior of three basic types of …

Synthesis Study: Development Of An Electronic Detection And Warning System To Prevent Overheight Vehicles From Impacting Overhead Bridges, Joseph V. Sinfield

JTRP Technical Reports

Overheight vehicle impacts with bridges are surprisingly common. The damage from collisions can range from minor to severe, and there is also evidence that some bridges are impacted multiple times, leading to the potential for cumulative damage effects. Thus there is a clear need to attempt to prevent overheight vehicle collisions with bridges.

This Synthesis Study provides a review of solutions that exist to detect and forewarn overheight vehicles and thereby prevent a collision, and specifically examines the breadth of available overheight vehicle detection technologies, the commercial availability of such equipment, and the experience of relevant DOTs with installed and …

Evaluation Of In-Situ Stiffness Of Subgrade By Resilient And Fwd Modulus, Daehyeon Kim, Yigong Ji, Nayyar Zia Siddiki

JTRP Technical Reports

Resilient modulus has been used for characterizing the stress-strain behavior of subgrade soils subjected to traffic loadings in the design of pavements. With the recent release of the M-E Pavement Design Guide, highway agencies are further encouraged to implement the resilient modulus test to improve subgrade design. A laboratory resilient modus test and a FWD test are usually used to obtain the resilient modulus of subgrade. However, the difference in the resilient modulus obtained from these two methods is considerably large due to the fact that these tests are conducted under different conditions. This difference gives engineers a significant confusion …

Use Of Dynamic Cone Penetration And Clegg Hammer Tests For Quality Control Of Roadway Compaction And Construction, Hobi Kim, Monica Prezzi, Rodrigo Salgado

JTRP Technical Reports

Soil compaction quality control presently relies on the determination of the in-place compacted dry unit weight, which is then compared with the maximum dry unit weight obtained from a laboratory compaction test. INDOT requires that the in-place dry unit weight for compacted soil be over 95% of the laboratory maximum dry unit weight. In order to determine the in-place dry unit weight, INDOT engineers generally use nuclear gauges, which are hazardous and also costly because of the required safety precautions. Thus, several alternative tests such as the Dynamic Cone Penetration Test (DCPT) and the Clegg Hammer Test (CHT) were introduced …

Geotechnical Design Based On Cpt And Pmt, Daehyeon Kim, Younjin Shin, Nayyar Siddiki

JTRP Technical Reports

This research presents the correlation of undrained shear strength based on the cone resistance from the cone penetration test (CPT) for clayey soils in Indiana. It utilized the field cone penetration test program including the CPT, the index test, the one dimensional test and the triaxial test. The cone factor, which is essential to reliable estimation of undrained shear strength from cone resistance, has been evaluated considering the plasticity index of soils. The cone factor is influenced by the penetration rate during the CPT and test methods that are used for obtaining the undrained shear strength. The rate effect of …

Monitoring And Predicting Traffic Induced Vertebrate Mortality Near Wetlands, J. Andrew Dewoody, Jamie M. Nogle, Melissa Hoover, Barny Dunning

JTRP Technical Reports

Animal-vehicle collisions are undesirable to the general public, to drivers, to insurance providers, to biologists, and presumably to the animals themselves. However, traffic-induced mortality (―roadkill‖) is difficult to mitigate in large part because scientists lack the empirical data required to understand the patterns and processes associated with roadkill. Roadkill is not randomly distributed in space or in time, but what are the primary determinants of roadkill? And do they differ across organismal groups? We monitored vertebrate roadkill at 6 wetland and 6 upland sites in Indiana twice a week for a period of 20 months to determine whether roadkill occurs …

Development Of A Framework For Ex Post Facto Evaluation Of Highway Project Costs In Indiana, Abhishek Bhargava, Samuel Labi, Kumares C. Sinha

JTRP Technical Reports

Researchers and engineers continue to ponder over the reliability of construction cost forecasts made at the early stages of project development. After a project has been incorporated in the statewide transportation improvement program, increasingly detailed estimates of its cost are prepared at the remaining stages of project development, namely, design estimate, engineer’s estimate, and bid estimate. The accuracy of such estimates has critical consequences on contract administration and asset management in general. Most agencies do not have a methodological framework to identify projects where final cost is likely to exceed the cost estimate, or where the cost estimate is likely …

Stress-Dilatancy Relation For Mohr-Coulomb Soils Following A Non-Associated Flow Rule, J Zhang, Rodrigo Salgado

Lyles School of Civil Engineering Faculty Publications

Rowe's stress–dilatancy relation for frictional (cohesionless) materials has been a cornerstone of soil mechanics. The original derivation of this relationship was based on incorrect energy minimisation considerations, but the relationship was proven later by De Josselin de Jong using friction laws, and has been confirmed by a large body of experimental results. In contrast, the validity of Rowe's stress–dilatancy relation for cohesive-frictional materials, which has also been used, although not as extensively, was never verified. This paper shows that Rowe's stress–dilatancy relation for Mohr–Coulomb soils (cohesive-frictional materials) is in fact incorrect. The paper also provides a correct stress–dilatancy relationship for …

Automated Pavement Condition Data Collection Quality Control, Quality Assurance, And Reliability, Ghim Ping (Raymond) Ong, Samy Noureldin, Kumares C. Sinha

JTRP Technical Reports

In recent years, state highway agencies have come to understand the need for high quality pavement condition data at both the project and network levels. At the same time, agencies also realize that they have become too dependent on contractors to ensure the quality of the delivered data without any means to independently assure the quality of these delivered data. This research study therefore aims to investigate the inherent variability of the automated data collection processes and proposes guidelines for an automated data collection quality management program in Indiana. In particular, pavement roughness data (in terms of IRI) and pavement …
