A statistical analysis of reinforced concrete wall buildings damaged during the 2010, Chile earthquake. Author links open overlay panel R. Jünemann a, J.C. de la Llera a, M.A. Hube a, ... The failure was characterized by concrete crushing and spalling of the concrete cover, thus generating a horizontal crack that initiates at the free end of ...

Nonlinear finite element (FE) analysis of reinforced concrete (RC) structures is characterized by numerous modeling options and input parameters. To accurately model the nonlinear RC behavior involving concrete cracking in tension and crushing in compression, practitioners make different choices regarding the critical …

About 2% of Reinforced Concrete (RC) buildings taller than nine stories suffered serious damage in structural walls during the 2010 Chile earthquake. The observed damage involved mostly crushing of concrete, buckling of vertical reinforcement, and opening of the horizontal reinforcement.

Unexpected failure modes were observed in RC walls in the 2010 Chile and 2011 New Zealand earthquakes. A peculiar failure mode, not previously reported in the structural engineering literature, was the brittle collapse of one of the structural walls of the 28-story Grand Chancellor Hotel in Christchurch, New Zealand.

Date: 1/1/1991. The web crushing strengths of 16 reinforced and prestressed concrete I-beams are reported. The principle variables of the test specimens are the ratio of yield force in the prestressed steel and the area of vertical stirrups. The test strengths are compared with the upper limit on shear strength given by the ACI Building Code ...

DOI: 10.14359/2775. Date: 9/1/1988. Abstract: Develops a methodology for the determination of the crushing strength of reinforced concrete membranes with two-way orthogonal reinforcement on the basis of theoretical considerations and experimental results. It differs from previous work in this area with respect to two principal features.

The housing construction in Chile is currently concentrated in reinforced concrete high-rise and medium-rise buildings, with 75% of the residential supply [45], due to the high density of city ...

The Mw 8.8 earthquake in 2010 in Chile provided valuable information regarding the damage and potential design code changes for reinforced concrete (RC) structures. Many modern RC buildings suffered severe damage, mainly in the form of concrete cover spalling, followed by longitudinal boundary bar buckling and concrete …

A wide range of reinforced concrete (RC) wall performance was observed following the 2010/2011 Canterbury earthquakes, with most walls performing as expected, but some exhibiting undesirable and

Damage observed in concrete walled buildings following major earthquakes since 1957 (Birely 2012). Modern slender wall test specimen (PW4) at the end of laboratory testing ...

The study showed that in Chile the observed lateral instability in slender walls was a secondary failure that occurred after initial crushing of the wall boundaries followed by subsequent buckling ...

Consequently, this research aims to study and validate a Non-linear Reinforced Concrete Wall (NRCW) finite element model using experimental results of …

Santiago Chile, January 9th to 13th 2017 Paper N° 2384 Registration Code: S-G1463184752 ADDRESSING BOUNDARY DESIGN FOR REINFORCED CONCRETE WALLS, BASED ON STUDIES OF THE 2010 CHILE EARTHQUAKE . K.

It is shown that the majority of structural damage in multistorey and high-rise buildings can be attributed to poor performance of slender shear walls, without confined …

The theory is applied to tests of reinforced concrete prisms and one Chilean building (Alto Huerto), which had a buckled wall following the 2010 Chile earthquake. Based on this study, it is ...

Steel jacketing in the plastic hinge region of the reinforced concrete column was one of the most well-known strengthening methods, particularly improving the flexural deformation and load-carrying capacities of the columns [4], [5].Fiber wrapping was also perhaps one of the most successful applications of fiber-reinforced polymer (FRP), due …

The severe damage and collapse of many reinforced concrete (RC) wall buildings in the recent earthquakes of Chile (2010) and New Zealand (2011) have shown that RC walls did not perform as well as ...

Reinforced Concrete (RC) shear walls are commonly used as lateral-force resistant systems for medium- to high-rise buildings in seismic countries such as Canada, Chile, Colombia, New Zealand, United States, and Turkey. ... Maffei et al. [9] showed that concrete crushing triggered the collapse, and bar buckling occurred after concrete …

Post-earthquake reconnaissance teams observed damage including buckling of reinforcing bars and concrete crushing at wall boundaries, overall wall buckling, and damage …

Highlights. •. Six ½-scale slender reinforced concrete walls were tested. •. The compressive-flexural failure mode observed in walls during 2010 Chile earthquake was reproduced experimentally. •. A 25% thickness reduction decreased the ultimate displacement and energy dissipation capacity of the tested walls. •.
