Experimental and analytical investigation of ponding load effects on a steel joist roof system

Creator:: Stark, Duncan
Abstract:: Ponding of water on roof systems leading to collapse causes expensive damage and jeopardizes the life safety of building occupants. Current building codes and design specifications for flat roof systems offer minimal guidance in designing for ponding loads. The present research investigated ponding load effects on a long span, lightweight...

Evaluating Worker Performance Using the Energy Concept

Creator:: Alotaibi, Abdulaziz M.
Abstract:: Over the decades, worker performance on construction projects has been a significant source of concern to be evaluated. Comprehensive studies have developed models for evaluating worker performance outside of the construction industry; however, minimal research has been conducted to evaluate worker performance in the construction industry. One of the reasons...

Numerical method for calculating construction pore pressures in embankments

Creator:: Steward, John Erwin
Abstract:: A computer program was developed for estimating construction pore pressures in embankments without drainage at any location in the embankment at any time during construction. This program incorporated a modification of the Hilf-Brantz method of pore pressure calculation and a finite element method of stress computation. Previous methods of calculating...

A Full-Scale Experimental Investigation of the Bearing Performance of Aggregate Pier-Supported Shallow Foundations

Creator:: Martin, John P.
Abstract:: Aggregate piers have been used for centuries, with increasing occurrence in the last few decades. Their usage has been driven by land development demand and enabled through equipment and engineering improvements. Understanding the principles controlling bearing capacities and serviceability performance has been an ongoing area of interest for structures supported...

Bearing capacity and immediate settlement of shallow foundations on clay

Creator:: Strahler, Andrew W.
Abstract:: Shallow foundations are extensively used to support structures of all sizes and derive their support from near surface soils. Thus, they are typically embedded up to a few meters into the soil profile. Designers of shallow foundations are required to meet two limit states: overall failure of the soil beneath...

Full-Scale Experimental Investigation of the Seismic Capacity of Reinforced Concrete Column-Footing Specimens Retrofitted with Titanium Alloy Bars Considering Effects of Soil-Structure Interaction on Vintage and Retrofitted Column-Footing Specimens

Creator:: McGinn, Logan
Abstract:: Reinforced concrete (RC) column-footing substructures are widely used to support bridges along critical transportation corridors in Oregon. Those built prior to 1971 were typically designed to resist only gravity loads. Therefore, they are vulnerable to damage or collapse during strong ground shaking. To prevent collapse, seismic retrofits have been developed...

Environmental durability of reinforced concrete deck girders strengthened with surface-bonded carbon fiber-reinforced polymer

Creator:: Sopal, Gautam Jayant
Abstract:: Long-term durability of surface-bonded carbon fiber-reinforced polymer (CFRP) for shear strengthening of reinforced concrete (RC) bridge members remains uncertain due to the limited field experience with these materials. This paper provides experimental results from the testing of full-scale RC bridge girder specimens after exposure to prolonged environmental exposure and combined...

Testing and Modeling of a Cross-Laminated Timber Pier-and-Spandrel Seismic Retrofit Solution for Unreinforced Masonry Buildings

Creator:: Engleson, Renee M.
Abstract:: Cross-laminated timber (CLT) is an attractive building material because it is renewable, promotes fast installation, and possesses a high strength-to-weight ratio. The use of CLT in seismic applications has become increasingly common with the development of post-tensioned CLT rocking wall lateral force resisting systems (LFRS). The CLT pier-and-spandrel system designed,...

Characterization of reinforced fill soil, soil-reinforcement interaction, and internal stability of very tall MSE walls

Creator:: Walters, James J.
Abstract:: In many geotechnical design situations involving tight right-of-way constraints, Mechanically Stabilized Earth (MSE) walls are often the most cost-effective and reliable earth retention technology among available alternatives. However, few well-documented case histories with detailed material testing, instrumentation programs and construction observation of performance are available in the literature. Despite the...

Evaluation of finite element techniques for soil reinforcement applications

Creator:: Berg, Ryan Robert
Abstract:: A literature review and a computer study are conducted to identify the requirements of finite element programs for the specific use of discrete analyses of reinforced soil structures. The utility of six commercially available programs are appraised with respect to the identified requirements. The results of the study are directed...
