Book excerpt: A proposed paradigm in engineering of bridges prone to the effects of multiple hazards calls for designing and detailing new bridges, as well as retrofitting existing bridges, so that an integrated structural concept provides protection against all credible hazards. This multi-hazard approach is believed to lead to structural systems that are optimal and offer a more uniform level of safety against various credible relevant hazard scenarios. Toward this objective, research was conducted to develop and experimentally validate two proposed structural concepts capable of achieving the objective of multiple hazard protection for highway bridges, namely Concrete Filled Double Skin Tube (CFDST) and Modified Steel Jacketed Columns (MSJC). CFDST is proposed as seismic and blast resistant column for new bridge multi-column bent. MSJC, on the other hand, is a "retrofit-of-the-retrofit" concept which adds blast protection to the capability of Steel Jacketed Column (SJC) already known to provide seismic resistance. Performance of CFDST is investigated both under cyclic pushover and blast tests whereas MSJC is tested under blast loading only using ℗ơ scale column prototypes. The energy dissipation of CFDST under cyclic loading was found to be excellent. Under credible blast scenario, CFDST deform in bending without significant loss in capacity to carry load. For near-contact explosion, another energy dissipation mechanism is engaged in the form of cross-section deformation. In both credible and near contact blast explosion, MSCJ is found to be able to develop large flexural deformations which are not achievable with non-modified SJC that are usually prone to direct shear failure. Equations are also presented to help designer predict the behavior of CFDST under blast and earthquake loads.^Comparison to the experimental data generated in this research as well to data available in the literature shows that those analytical results are accurate, and in some instances conservative.

Book Synopsis Earthquake Resilient Bridge Columns Utilizing Damage Resistant Hybrid Fiber Reinforced Concrete by : William Dean Trono
Download or read book Earthquake Resilient Bridge Columns Utilizing Damage Resistant Hybrid Fiber Reinforced Concrete written by William Dean Trono and published by . This book was released on 2014 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern reinforced concrete bridges are designed to avoid collapse and to prevent loss of life during earthquakes. To meet these objectives, bridge columns are typically detailed to form ductile plastic hinges when large displacements occur. California seismic design criteria acknowledges that damage such as concrete cover spalling and reinforcing bar yielding may occur in columns during a design-level earthquake. The seismic resilience of bridge columns can be improved through the use of a damage resistant hybrid fiber reinforced concrete (HyFRC). Fibers delay crack propagation and prevent spalling under extreme loading conditions, and the material resists many typical concrete deterioration mechanisms through multi-scale crack control. Little is known about the response of the material when combined with conventional reinforcing bars. Therefore, experimental testing was conducted to evaluate such behaviors. One area of focus was the compression response of HyFRC when confined by steel spirals. A second focus was the tensile response of rebar embedded in HyFRC. Bridge columns built with HyFRC would be expected to experience both of these loading conditions during earthquakes. The third focus of this dissertation was the design, modeling, and testing of an innovative damage resistant HyFRC bridge column. The column was designed to rock about its foundation during earthquakes and to return to its original position thereafter. In addition to HyFRC, it was designed with unbonded post-tensioning, unbonded rebar, and headed rebar which terminated at the rocking plane. Because of these novel details, the column was not expected to incur damage or residual displacements under earthquake demands exceeding the design level for ordinary California bridges. A sequence of scaled, three dimensional ground motion records was applied to the damage resistant column on a shaking table. An equal scale reinforced concrete reference column with conventional design details was subjected to the same motions for direct comparison. Compression tests showed that the ductility of HyFRC is superior to concrete in the post-peak softening branch of the response. HyFRC achieved a stable softening response and had significant residual load capacity even without spiral confinement. Concrete required the highest tested levels of confinement to achieved comparable post-peak ductility. Tension tests showed that HyFRC provides a substantial strength enhancement to rebar well beyond their yield point. Interesting crack localization behavior was observed in HyFRC specimens and appeared to be dependent on the volumetric ratio of rebar. The damage resistant HyFRC bridge column attained its design objectives during experimental testing. It exhibited pronounced reentering behavior with only light damage under earthquake demands 1.5 to 2.0 times the design level. It accumulated only 0.4% residual drift ratio after seven successive ground motions which caused a peak drift ratio of 8.0%. The conventional reinforced concrete column experienced flexural plastic hinging with extensive spalling during the same seven motions. It accumulated 6.8% residual drift ratio after enduring a peak drift ratio of 10.8%.
