Abstract: This report presents the results of an analytical and experimental study on the use of Concrete-Filled Double Skin Tubes (CFDST) and Modif ed Steel Jacketed Bridge Columns (MSJBC) to provide blast and seismic resistance (from a multi-hazard perspective). First, the ability of CFDST columns to provide satisfactory seismic performance is verified by cyclic inelastic testing of quarter scaled specimens. Then, their blast resistance is investigated through two series of tests, respectively conducted at the MCEER ECLIPSE testing facility in Buffalo and at the U.S. Army Corps of Engineers Research and Development Centerís Facility in Vicksburg, Mississippi. Closed-form equations are also presented for the design of CFDST and MSJFC and to predict their response (lateral deflection and extent of denting) during blast scenarios.

Property Modification Factors for Seismic Isolators: Design Guidance for Buildings
W.J. McVitty and M.C. Constantinou
MCEER-15-0005 | 6/30/2015 |242 pages | $35
Keywords: seismic isolation, ASCE 7-2016 Standard, system property modification factors, bounding methods of analysis
Abstract: This report provides guidance on the application of the provisions of the 2016 ASCE 7 Standard for the analysis and design of seismically isolated buildings. These new provisions introduced a systematic approach for the determination of the bounding values of the mechanical properties of the isolators on the basis of experimental data of prototype isolators and considerations for the effects of the environment, aging and uncertainty. The report presents an overview of the concept of system property modifi cation factors that is used in the establishment of the bounding values and proceeds with two systematic examples, one for an elastomeric and one for a sliding isolation system. Moreover, the new provisions are critically reviewed for consistency between the requirements for establishing bounding values and the prescribed acceptance criteria in the testing of prototype isolators. Changes are proposed to the standard to avoid inconsistencies.
