PreCast Concrete in Earthquake Regions AboutCivilOrg

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

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.

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-

Recent Advances in the Design of Prestressed Concrete Piles in Marine Structures in Seismic Regions. This CD consists of 8 papers that were presented at a technical session sponsored by ACI Committees 357, 423, and 543 at the ACI Convention in Minneapolis, MN, in April 2013.

Section 11-8 Design Guidelines of Precast Prestressed Girder1 s • Furthermore, precasprecast girders can be more effective and economical when the girder quantity is large and details are repeatable. Project Engineers encouraged to consider precast prestressed concrete girder superstructures as an a lt ernat ive during the planning phase.

concerns in application of precast concrete in regions with moderate-to-high seismicity is to ensure adequate performance of the connection between precast members. The traditional cast-in-place seismic design philosophy relies on formation of plastic hinges during an earthquake

Recent significant advances have been made in design, analysis and construction technologies for earthquake resistant concrete structures and have led to the need for an up-to-date survey of current practice. Concrete Structures in Earthquake Regions: Design and Analysis provides this survey.

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.

Bulletin of New Zealand Earthquake Engineering - Volume 49, Issue 3 Sep 2016. This paper presents findings from the first phase of testing at the University of Canterbury on seismic performance of emulative connections for Accelerated Bridge Construction (ABC) in regions of moderate to high seismicity. Emulative connections between precast

level unbonded post-tensioned precast concrete coupling beam subassembly and typical cross-section is shown in Figure 1(b). The subassembly includes the precast coupling beam and the adjacent cast-in-place reinforced concrete walls at a floor level as indicated by the shaded region in Figure 1(a).

The final report that accompanies this appendix is a technical resource that provides background information on the use of a precast bent system for use in high seismic regions. The system is designed for, and intended to be used with, prestressed girder bridges that are built integrally with the supporting intermediate piers.
