OBJECTIVE To test the hypothesis that stress generated by the Newcastle earthquake led to increased risk of heart attack and coronary death. DESIGN A natural experiment. SUBJECTS People living in the Newcastle and Lake Macquarie local government areas of New South Wales, Australia. INTERVENTION At 10.27 a.m. on 28 December 1989 Newcastle was struck by an earthquake measuring 5.6 on the Ri...

OBJECTIVES To examine the development and determinants of long-term outcomes for earthquake victims with amputations, including physical function, pain, quality of life and life satisfaction. DESIGN Prospective cohort study with 2-3 measurement points. SUBJECTS A total of 72 people who underwent amputations following the 2008 Sichuan Earthquake and resided in Mianzhu County, Sichuan Provinc...

The vulnerability of the UHV porcelain arrester is very high under strong earthquake. To rise seismic reliability of the UHV porcelain arrester, a new type lead damper, which is a new patent product, is installed at the bottom of the equipment. To investigate the damping effect of the dampers, the experimental research and finite element analysis on seismic behavior of the UHV porcelain arreste...

OBJECTIVES This study examined personality, coping styles, and psychosomatic characteristics and their relationships in bereaved and non-bereaved earthquake survivors. STUDY DESIGN Cross-sectional survey. METHODS A survey was conducted with a sample of 102 non-bereaved survivors and 79 bereaved survivors from Mianyang, Anyang, and similar districts 2 weeks after Wenchuan earthquake. Survivo...

The use of “ductile seismic frames,” whose proper seismic behavior largely depends upon construction details and specific design rules, may do not always lead to effective seismic resistant structures, as dramatically denounced by the famous Chinese artist Ai Weiwei in his artwork Straight. The artwork (96 t of undulating metal bars that were salvaged from schools destroyed by the 2008 Sichuan,...

One of the most important factors affecting the design of the structures, is the impact of the earthquake loadings on the forces and the design displacements. Nevertheless, the influences of the near structures on the existing buildings, that sometimes can cause great changes in forces and displacements, can never be forgotten. Thus, the induced displacement in the adjacent buildings of a newly...

Windmill, machine that converts wind into useful energy. This energy is derived from the force of wind acting on oblique blades or sails that radiate from a shaft. The turning shaft may be connected to machinery used to generate electricity. The present paper makes an attempt to show the effect of wind and earthquake load on tubular type windmill and its foundation considering hard, medium and ...

Bridges are essential lifelines for transportation networks during and after an earthquake event, providing routes for emergency response and evacuations. For this reason, bridge fragility modeling has been a major focus in earthquake research, as fragility analysis aids in the post-event determination of possible damage of bridges as well as in pre-event mitigation planning. While fragility an...

We performed simulations of ground motions in Mexico City expected for large earthquakes in the Guerrero seismic gap in Mexico. The simulation method uses as empirical Green's functions the accelerograms recorded in Mexico City during four small to moderate earthquakes (8 Feb. 1988, M s = 5.8; 25 April 1989, M w = 6.9; 11 May 1990, M w = 5.5; and 31 May 1990, Mw = 6.0) in the Guerrero gap. Beca...
