In 1972, J.T.P. Yao introduced the modern control theory into vibration control of civil structures (Yao, 1972), which started the new era of research on structural active control in civil engineering field. During the development of nearly 40 years, Active Mass Driver/Damper (AMD) control, with the better control effect and cheaper control cost, has taken the lead in various active control occ...
The impact of emotions on organizational performance during crisis response is examined. Data is drawn from the after action reports of individuals in two American Red Cross teams, one faced with responding to Hurricane Hugo and the other to the Loma Prieta Earthquake. Based on the texts generated by individuals in the American Red Cross who took part in these situations we examine whether the ...
This paper explores the effects of the 1995 Hanshin-Awaji Earthquake on the wages of people in the area of the earthquake over the 17 years after its occurrence and identified which part of the wage distribution has been most affected by this event by comparing the wage distributions of disaster victims and non-victims. To do this, we used three decomposition methods, developed by (i) Oaxaca (1...
Introduction: Earthquake is one of the commonest natural disasters and sometimes the most dangerous event in the world. In Iran, because of being on Alp-Himalaya earthquake belt, earthquake is common. In earthquake events, hospitals are as the first centers that their providing suitable and timely healthcare are determinant and can save lives and reduce mortalities. Also, having knowledge about...
on april 15, 1979,a destructive earthquake struck the southwestern part of yugoslavia, in which the total damage exceeded 2.7 billion dollars. in this paper, major engineering lessons learned in this earthquake are discussed and illustrated with representative photographs. the main causes of failure of masonary and reinforced concrete buildings are pointed out. effect of architectural design on...
On 12 May 2008, the 8.0-magnitude Wenchuan earthquake occurred in Sichuan Province, China, triggering thousands of landslides, debris flows, and barrier lakes, leading to a substantial loss of life and damage to the local environment and infrastructure. This study aimed to monitor the status of geologic hazards and vegetation recovery in a post-earthquake disaster area using high-resolution aer...
Earthquakes can cause catastrophic accidents to the railroads in terms of serious facility damages and large number of passenger fatalities and injuries. To reduce earthquake risk, various safety counter-measures can be employed. Among them, performing an accelerated construction program of track strengthening, retrofitting rail viaducts, installing warning systems, and improving the braking sy...
Requirements engineering (RE) is concerned with the identification of stakeholders' needs concerning a future system, the specification of services and constraints that satisfy these needs, and the assignment of the resulting requirements to agents such as humans, hardware devices, and software components. Functional requirements describe what functions must be provided to satisfy the stakehold...
The primary goal of NEESgrid data/metadata effort is to work collaboratively with NEESgrid System Integrator team and the NEES community and to help define data requirements and needs for the George Brown Jr. Network for Earthquake Engineering Simulation instigated by the National Science Foundation. The NEESgrid promotes NEES as a distributed virtual laboratory for earthquake engineering resea...
A seismic risk assessment is often performed on behalf of a buyer of large commercial buildings in seismically active regions. One outcome of the assessment is that a probable maximum loss (PML) is computed. PML is of limited use to real-estate investors as it has no place in a standard financial analysis and reflects too long a planning period for what-if scenarios. We introduce an alternative...
