PEER Testbed Study on a Laboratory Building: Exercising Seismic Performance Assessment [PDF]

, 2005
From 2002 to 2004 (years five and six of a ten-year funding cycle), the PEER Center organized the majority of its research around six testbeds. Two buildings and two bridges, a campus, and a transportation network were selected as case studies to ...

Evaluation the behavior of seismic bracing connections based on clearance [PDF]

Journal of Structural and Construction Engineering, 2018
Today one of the most common systems for resisting lateral forces (wind and earthquake) is special concentrically braced frames (SCBF). Out of plane buckling in compression causes large inelastic flexural deformations in gusset plate.

Is It Possible to Predict Strong Earthquakes?

, 2014
The possibility of earthquake prediction is one of the key open questions in modern geophysics. We propose an approach based on the analysis of common short-term candidate precursors (2 weeks to 3 months prior to strong earthquake) with the subsequent ...

Seismic vulnerability of churches in Faial and Pico islands, Azores [PDF]

, 2012
Earthquakes represent one of the main cause of serious damage and loss of historic and architectural heritage. Interventions to preserve these building should start with a careful knowledge and assessment of their seismic vulnerability, in order to ...

Electro-Magnetic Earthquake Bursts and Critical Rupture of Peroxy Bond Networks in Rocks

, 2006
We propose a mechanism for the low frequency electromagnetic emissions and other electromagnetic phenomena which have been associated with earthquakes. The mechanism combines the critical earthquake concept and the concept of crust acting as a charging ...

Mechanics of earthquakes [PDF]

, 1994
An earthquake is a sudden rupture process in the Earth’s crust or mantle caused by tectonic stress. To understand the physics of earthquakes it is important to determine the state of stress before, during, and after an earthquake.

Application of the Endurance Time Method in the Seismic Assessment of Moment-Resisting Reinforced Concrete Frames with Setbacks [PDF]

مدل‌سازی پیشرفته در مهندسی عمران
Nowadays, many buildings around the world exhibit height irregularities. Given that higher vibration modes can significantly influence the responses of irregular frames, it is essential to investigate the seismic behavior of these structures.
