Seismic behavior of double walls with continuity reinforcement

2015-07-21
The conventional precast construction has deficiencies especially related to its connections between structural elements. Hence, its use in earthquake zones has been limited. However, the seismic performance of these systems can be improved by a semi-precast system, namely the double wall system. In this structural system, both precast and cast-in-situ concrete elements are utilized during the construction period, i.e. precast concrete shells are benefitted as a formwork to place cast-in-situ concrete. In this way, monolithic building elements, which finally show the same effectiveness as cast-in-situ concrete walls and slabs can be constructed. In this study, reversed cyclic test results for the double walls are reported. The main objective of the experimental program is to compare the seismic response of two double walls, one cast monolithically, the other one composed of two walls constructed side-by-side and having monolithically cast concrete at the central region along with the continuity reinforcement between the two separate wall elements. Test results demonstrate that the use of continuity reinforcement between adjacent double walls ensure monolithic response with increased stiffness and energy dissipation characteristics.

Safkan, Ismail; Sensoy, Serhan; Ertuğrul, Zehra (2017-12-01)
Corrosion related deterioration of reinforced concrete buildings is often studied by the structural engineering community. The literature reveals the fact that modelling of deteriorated members requires a unique consideration due to brittle section behaviour. The late adaptation of seismic regulation rules and lack of decent quality construction material supply results a vulnerable building category in the island of Cyprus. This paper examines the vulnerable building category by combining concrete strength ...

Özçelik, Ramazan; Binici, Barış; Department of Civil Engineering (2011)
This thesis examines the seismic internal retrofitting of existing deficient reinforced concrete (RC) structures by using structural steel members. Both experimental and numerical studies were performed. The strengthening methods utilized with the scope of this work are chevron braces, internal steel frames (ISFs), X-braces and column with shear plate. For this purpose, thirteen strengthened and two as built reference one bay one story portal frame specimens having 1/3 scales were tested under constant grav...
Seismic Strengthening with Precast Concrete Panels - Theoretical Approach
Baran, Mehmet; Canbay, Erdem; Tankut, Tugrul (2010-01-01)
An economical, structurally effective and practically applicable seismic retrofitting technique has been developed on the basis of the principle of strengthening the existing hollow brick infill walls by using high strength precast concrete panels. The technique would not require evacuation of the building and would be applicable without causing much disturbance to the occupant. For this purpose, a total of eighteen reinforced concrete frames with hollow brick infill walls were tested under reversed cyclic ...
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...
Energy based evaluation of RC frame structures
Azizi, Mahyar; Erberik, Murat Altuğ; Department of Civil Engineering (2019)
Nowadays, earthquake and structural engineers perceive that conventional seismic design method, which is based on force and strength, is not an adequate way of designing structures under ground motions. The reason is that the conventional seismic design method does not pay enough attention to inelastic displacements, plastic behavior of structures and duration of seismic motion. At the present time, there are new and popular alternatives to the force-based approach like displacement-based method, in which t...
