  • Response of frames seismically protected with passive systems in near–field areas

    The present paper analyses the behaviour of moment resisting frames in reinforced concrete subject to earthquakes recorded in near–field areas. In these areas, the signals show impulsive–type accelerograms, with velocity and displacement peaks higher than in far–field zones especially for the fault–normal component of the ground motion velocity in the direction of propagation of the wave, which ...

  • Seismic study at the Pacific and Atlantic locks of the panama canal case study

    Panama Canal Zone Grupo Unidos Por el Canal (GUPC) was tasked with characterizing subsurface conditions within the Third Set of Locks Project for the Panama Canal. In support of their characterization efforts, GUPC requested that seismic geophysical data be acquired at four locations within the project area.  These locations include portions of the: Miraflores ...

  • Estimating ground motion levels in earthquake damage investigations: a framework for forensic engineering seismology

    Earthquake–resistant design matches performance targets of structures and facilities with defined levels of ground shaking. Structural failure in an earthquake may result from higher ground motions or from poor design and construction. In legal disputes in such circumstances experts are required to infer the ground–motion levels at the site, if there are no ground–motion ...

  • Fragility of underground pipeline under high levels of ground motion

    Damage estimation relationships have been proposed based on seismic ground motions and pipeline damage records from past earthquakes as a technique for understanding damage in future seismic hazards. This kind of relationship is formulated by correcting the standard damage relationship shown by the amount of damage from seismic ground motion with coefficients such as pipe materials and ground ...

  • Early warning of disasters: Facts and figures

    Lucy Pearson looks at early warning systems for disasters, their uses and limits, and what accounts for the gap between warning and action. Through history disasters have destroyed lives and livelihoods, killing people and damaging homes and businesses. Disasters in the past 35 years have taken an estimated 2.5 million lives and cost more than US$1.5 billion, mainly in developing ...

  • Interview with Ronald Ebelhar, 2015 Chairman of the ASTM Board

    Ron Ebelhar has provided leadership in civil engineering projects and ASTM technical committee work since the 1970s. This year, he brings his experience to his elected position as chairman of the ASTM board of directors. You have worked on dozens of engineering projects since getting your degrees in civil engineering. What are some of the most interesting and challenging jobs you ...

  • The end and beginning of the Arctic

    At the top of the world, it’s time to get ready for a new future. In the winter of 2013–14, hundreds of milk-white birds with luminous yellow eyes and wingspans of up to 5 feet descended on beaches, farmers’ fields, city parks and airport runways throughout southern Canada and the United ...
