Applying Modern Technology In The Preservation Of Historic Concrete Picnic Tables, Michele M. Anderson
Applying Modern Technology In The Preservation Of Historic Concrete Picnic Tables, Michele M. Anderson
Civil Engineering ETDs
Preserving historical concrete structures recognizes the work and skills of past generations and allows the communities surrounding these pieces of history the opportunity to enjoy the character and purpose of their construction. Restoration of concrete picnic tables, constructed in the 1930s by the Civilian Conservation Corps, required researching materials and methods of construction during the original construction period. Eight decades of environmental and weather cycles did not decay the historic structures. Acts of vandalism destroyed the purpose of the tables and benches. Restoration of the historic picnic tables required extensive literature review for the materials and methods used during the …

In this study, a novel discrete Peridynamics framework called the “State-Based Peridynamic Particle Model (SPPM)” is introduced. In this approach, a solid body is simulated by neither solving differential equations nor integral equations; instead, the simulation is accomplished by directly solving discrete systems of equations using finite summations. SPPM is formulated for a random distribution of particles, hence, it can be considered as a meshfree method. The assumptions of continuity and homogeneity are not necessary for this approach. The SPPM is a generalization of the “State-Based Peridynamic Lattice Model (SPLM)”. In the SPLM formulation, for sake of simplicity and computational …
