The validity of centrifuge modeling of soil systems is investigated by means of a “yielding trapdoor” setup similar to the one used by previous researchers for examining soil arching. A modeling-of-models exercise is thus carried out in accordanc

Background and historical perspective are provided on the development of the earthquake loss estimation methods of the HAZUS technology (HAZUS Earthquake), the various modules of HAZUS Earthquake are described, and key concepts of these methods are s

A relatively simple rigid plastic multiblock computational model has been developed to predict the permanent seismic displacement of mechanically stabilized earth (MSE) walls. The model formulation was based on many observations made from a series of

Altogether six mechanically stabilized earth walls were subjected to many base excitations on the National Geotechnical Centrifuge at the Univ. of California, Davis. The walls supported dry cohesio...

Probabilistic methods are potentially useful in four stages of a typical project: site characterization and evaluation, evaluation of designs, decision making, and construction control. In evaluation of projects, it can be useful to express risk nume

A two-dimensional (2D) finite element analytical model is developed to analyze the seismic response of rigid highway bridge abutments, retaining and founded on dry sand. A well verified finite element code named FLEX is used for this purpose. The pro

This paper describes methods for estimating building losses that were developed for the FEMA/NIBS earthquake loss estimation methodology (Whitman et al., 1997). These methods are of a new form and represent a significant step forward in the predictio

This paper summarizes the development of a geographic information system (GIS)-based regional loss estimation methodology for the United States funded as part of a four-and-one-half year project by the Federal Emergency Management Agency (FEMA) throu

Every day actions are taken that reduce the risks associated with earthquakes. This national, amorphous but action-oriented effort is NERRP (different from nehrp—the federally-funded information-gathering-and-disseminating effort). There is today n

The seismic response of anchored bulkheads with saturated backfill has been simulated in a series of centrifuge tests involving various intensities of shaking, two relative densities of the backfill and two pore fluids with different viscosities. The
