Blume Professor Emeritus of Engineering at Stanford University and a leading expert in structural design and earthquake engineering, died on 16 April 2012, just a few days after his 72nd birthday. Helmut had been diagnosed with a brain tumor less than three months earlier, and under the loving care of his wife Michele, he remained optimistic and in good spirits throughout his cancer treatment.

Se presenta en este trabajo una descripción dela red y los resultados que se han obtenido en sus primeros tres años de operación, en los que ha registrado 16 eventos sísmicos. Se describen las técnicas empleadas para el análisis de las señales y la interpretación deresultados, así como las conclusiones que de ellos se derivan acerca del comportamiento sísmico del edificio. El movimiento inducido en la base de la estructura tiene amplitudes mucho menores que el registrado en campolibre, para el intervalo de períodos que son críticos para su respuesta sísmica. El movimiento en distintos puntos de la cimentación presenta amplitudes semejantes pero diferencias de fases, y la estructura tiene una muymoderada amplificación del movimiento de su base. Diversas partes de la estructura tienden a vibrar de manera independ...

The proposed intensity measure is based on the peak interstory drift demand computed using a simplified continuous model that consists of a combination of a flexural beam and a shear beam. This new intensity measure accounts for the influence

An inelastic displacement ratio is defined as the ratio of the maximum lateral inelastic displacement demand of a structure to the maximum lateral elastic displacement demand. ...

Inelastic displacement ratios are computed for single-degree-of-freedom systems undergoing different levels of ...
