The infrequent nature of earthquakes in the Central and Eastern United States (CEUS), and the fact that none with intensity comparable to the New Madrid sequence of 1811-12 has occurred in the past century, have caused the earthquake hazard in the CEUS to be neglected until quite recently. The performance of reinforced concrete (RC) frames in the CEUS may be deficient if they are subjected to earthquakes that are believed to be plausible in the New Madrid Seismic Zone (NMSZ). This study presents a set of probability-based tools for seismic vulnerability and risk assessment of such gravity load designed (GLD) RC frames, and uses these tools to evaluate the seismic vulnerability of RC frames that are representative of the building inventory in Memphis, Tenn.-the largest population center close to the NMSZ. This evaluation indicates that traditional GLD RC frames have a substantial probability of suffering life-threatening damage or collapse in the event that they are subjected to earthquake demands stipulated in recent seismic design regulations such as ASCE Standard 7-05.

Performance-based seismic rehabilitation of damaged reinforced concrete buildings
Sucuoğlu, Haluk; Gunay, MS (American Society of Civil Engineers (ASCE), 2004-10-01)
A building stock consisting of 130 medium-rise reinforced concrete buildings were damaged moderately during the recent earthquakes in Turkey. These buildings were rehabilitated by using simple, cost-effective methods where the newly added shear walls comprised the primary lateral load resisting system. In the presented study, different seismic performance evaluation procedures are tested first on the samples of damaged buildings for predicting their observed performances. Then the expected performances of t...
Seismic performance of multisimple-span bridges retrofitted with link slabs
Caner, Alp; Zia, P. (American Society of Civil Engineers (ASCE), 2002-03-01)
During earthquakes multisimple-span bridges are vulnerable to span separation at their expansion joints. A common way of preventing unseating of spans is to have cable or rod restrainers that provide connections between adjacent spans. Alternatively, dislocation of the girders can be controlled with a link slab that is the continuous portion of the bridge deck between simple spans. Seismic retrofit with link slab should be more cost-effective than the existing methods when it is performed during redecking o...
RESISTANCE MECHANISMS IN RC BUILDING FRAMES SUBJECTED TO COLUMN FAILURE
Sucuoğlu, Haluk; ALTIN, S (American Society of Civil Engineers (ASCE), 1994-03-01)
There is a damage potential for the columns of building frames due to either unexpected causes such as vehicle impact, boiler explosion, or terrorist attack, or due to design or construction deficiencies aggravated by an earthquake, severe wind, or excessive foundation movement. This paper investigates the redistribution paths of released forces resulting from a column failure and identifies the basic structural defense mechanisms developed in a damaged building frame. Extensive analytical studies revealed ...
Energy based seismic performance assessment of reinforced concrete columns
Acun, Bora; Sucuoğlu, Haluk; Department of Civil Engineering (2010)
Severe seismic events in urban regions during the last two decades revealed that the structures constructed before the development of modern seismic codes are the most vulnerable to earthquakes. Sub-standard reinforced concrete buildings constitute an important part of this highly vulnerable urban building stock. There is urgent need for the development and improvement of methods for seismic performance assessment of existing reinforced concrete structures. As an alternative to current conventional force-ba...
Seismic vulnerability, behavior and design of tunnel form building structures
Balkaya, C; Kalkan, E (Elsevier BV, 2004-12-01)
Multi-story reinforced concrete tunnel form buildings are one of the common structural types in regions prone to high seismic risk due to the buildings inherent earthquake resistance and ease of construction. Despite their good performance during earthquakes in 1999 in Turkey, and abundance of such structures scattered worldwide, current seismic codes and design provisions provide insufficient guidelines for their seismic design. As a compensatory measure, a series of modal and nonlinear static analyses are...
