Evaluation of Seismic Performance of Reinforced Concrete Frames

Abstract: Experimental results from a series of earthquake simulations on a one-quarter scale model of a moment-resisting reinforced concrete frame are presented. Using the test results, some of the U.S. seismic design provisions are examined. It is observed that even though drift capacity was amply provided, the magnitude of drift was not adequately anticipated by the design process. Moreover, the structure was several times stronger than required by the code design forces. The contributions of floor slab, actual material strengths, and detailing requirements are identified as the significant sources of overstrength. The effect of these parameters on the overall performance is evaluated.

Seismic field methods for in situ moduli

Abstract: : The design and evaluation of the response of engineered structures to earthquake excitation have increased the current use of seismic field studies to determine soil properties at low strain levels for in situ materials. Buildings, nuclear power plants, major earth structures, locks, and concrete dams are now being studied using finite element techniques and modal or time- step analyses. The validity of these studies and the interpretation of their results depend on a reliable assessment of input values for in situ foundation properties. This report presents procedures for planning seismic field investigations for the determination of soil properties. Emphasis is placed on the selection of appropriate seismic techniques to obtain sufficient redundant data with which to establish internal consistency for reliable assessments of determined properties.
