Abstract
On 25 April - 12 May 2015, a series of large earthquakes struck the north-central part of Nepal, causing not only a substantial number of casualties, but also heavy damage to the building structures and infrastructure facilities. Up to now, most of seismic reconnaissance studies about this event have attributed the structural damage and life losses to the relatively loose implementation of the building design codes in Nepal, as most of those damaged structures were largely owner-built. Based on the quite limited ground motion data, this paper investigated the primary characteristics of the Nepal earthquake sequence. It is highlighted that the pulse-like features are significant at both the soft and rock sites, which is also responsible for the unique characteristics of the main-shock ground motions other than site effects.
期刊介绍：
The Earthquakes and Structures, An International Journal, focuses on the effects of earthquakes on civil engineering structures. The journal will serve as a powerful repository of technical information and will provide a highimpact publication platform for the global community of researchers in the traditional, as well as emerging, subdisciplines of the broader earthquake engineering field. Specifically, some of the major topics covered by the Journal include: .. characterization of strong ground motions, .. quantification of earthquake demand and structural capacity, .. design of earthquake resistant structures and foundations, .. experimental and computational methods, .. seismic regulations and building codes, .. seismic hazard assessment, .. seismic risk mitigation, .. site effects and soil-structure interaction, .. assessment, repair and strengthening of existing structures, including historic structures and monuments, and .. emerging technologies including passive control technologies, structural monitoring systems, and cyberinfrastructure tools for seismic data management, experimental applications, early warning and response
