A cost-effective integral bridge system with precast

Such structures are not frequently used in high seismic regions due to lack of design guides and overly conservative design approaches. A half-scale, 17.8 m (58.5 ft) long test unit modeling a portion of a prototype bridge incorporating a concrete column, ten I-shaped precast concrete girders, and an inverted-tee concrete

Collapse rates of reinforced concrete structures during

This case study focuses on the evaluation of the collapse rates of various types of reinforced concrete structures (residential and industrial) as observed from the data collected in Romania after the M w 7.4 Vrancea earthquake of March 4, 1977. The results of the analyses show that the largest collapse rates were attributed to elevated reinforced concrete silos and water tanks.

Earthquake vulnerability of city regions based on building

India positions among the top five nations which have been hit by the most number of catastrophic events in the preceding decade. The current study is focussed on seismic vulnerability assessment of buildings by FEMA (Federal emergency management agency) guidelines (HAZUS methodology) in selected regions of a Tier II city of south India-Coimbatore (falling in Zone III as per BIS 1893-

Effect of Connection Deficiency on Seismic Performance of

The quality of precast concrete (PC) component connections is one of the main factors that affect the seismic reliability of PC structures. China is developing PC structures in high seismic regions, and it is important to assess the effect of connection deficiency on seismic performance of PC structures.
