Atkinson-Noland & Associates worked with Bridge Diagnostic, Inc. to evaluate the performance of the historic Ames Street Bridge in Dedham, Massachusetts during the strengthening phase of the structure. Live load tests were conducted on the bridge before and after strengthening to evaluate the efficiency of the selected rehabilitation method. Displacement and strain were monitored at several critical locations along the arch barrels using Linear Variable Differential Transformer (LVDT) displacement sensors and surface - mount strain transducers. A finite element study was performed to understand the complex behavior of the multi-span masonry arch bridge. A long-term monitoring system was installed to evaluate the bridge behavior over time
The church was built in 1917 of concrete masonry blocks that were reportedly cast on site by members of the church. The main problem with the church exterior is the delamination of the exterior skin of the concrete block.
Constructed in 1934, the "Old Senior Hall" building was built with a structural steel frame, concrete and gypsteel floors and roof, and a reinforced concrete foundation. The exterior walls were built using a brick masonry façade over a clay tile backup with limestone sills, coping, and accents. Active corrosion of main structural members was discovered in the late 1990's, and a plan was developed to renovate the building to address structural concerns. Atkinson - Noland conducted a full exterior condition survey, including use of nondestructive tests to identify the extent of steel corrosion, evaluate masonry performance, and identify potential repair items. Results of this study were used to plan repairs and any necessary strengthening.
The Health Center building on the Milton Hershey School campus was designed in 1932 as load-bearing masonry construction with steel framing used to support floor and roof loads and loose steel lintels spanning over window and door openings. Atkinson-Noland & Associates was retained to conduct an investigation of the exterior load-bearing masonry walls and structural steel framing for the purpose of identifying typical as-built conditions as well as the locations and severity of any deterioration.
The 16th Street Mall in downtown Denver, Colorado is a pedestrian and transit mall that extends for more than a mile along 16th Street connecting people to major businesses, hotels, restaurants, and retail. Recently, the street mall pavers have experienced a substantial number of loose and cracked granite pavers. Atkinson-Noland & Associates conducted an extensive investigation at the 16th Street Mall granite tile pavers to determine the causes of distress in the paving system. We also helped develop appropriate solutions to paver debonding, slip-resistance, aesthetics, and maintenance.
Atkinson-Noland & Associates was a principal investigator on a three-year project evaluating different techniques for repair and retrofit of unreinforced masonry structures. Old masonry construction was simulated in the laboratory, and the test specimens were strengthened by installation of internal reinforcement or repaired by grout injection.
A six-story condominium building was constructed using load-bearing, concrete masonry with a clay brick masonry veneer. Specifications required that the collar joint be filled during construction; however, the contractor built the masonry without grouting the collar joint. Subsequent negotiation determined that the masonry must be reconstructed with a filled collar joint.
Right: Construction began on the Piedras Blancas Light Station in 1874. The site now includes two of the original historic structures-a lighthouse building completed in 1875 and a fog signal building completed in 1906. The lighthouse building was originally 115 feet tall, including a first-order Fresnel lens manufactured in Paris, France.
A two-story masonry building in the historical district of Cripple Creek, Colorado was assessed to determine its present condition. The building was to be retrofitted as a casino but was suffering from over 100 years of weathering in a severe climate and recent neglect.
