Experimental and numerical studies on block type quay walls under dynamic loading

Karakuş, Hülya
In this study, the dynamic response of block type quay wall was investigated by 1 g shaking table tests for one, two, three block(s) for different frequencies using two different saturated granular backfill materials (Soil 1 and Soil 2). During the experiments accelerations, pore pressures, soil pressures and displacements are measured. Distribution of the fluctuating component of total saturated soil pressure and application point, friction coefficients between the rubble-block and block-block are determined experimentally to form a base for the “performance based design method”. The experimental studies completed with numerical studies carried out using PLAXIS V8.2 software program. Comparisons of all soil pressure and horizontal displacement results show that experimental conditions are simulated succesfully with numerical study. A case study was carried out with the site data of Derince Port, block type quay wall which is damaged during Eastern Marmara Earthquake, 1999. Horizontal displacement result obtained by PLAXIS V8.2 for Derince Port, block type quay wall is in very close agreement with the site measurements. Results of measurements for displacement are discussed in view of “acceptable level of damage in performance based design” given in PIANC (2001). The result of the study performed for Derince Port, block type quay wall using numerical model is a good evidence of the reliability of the definitions of damaged levels given in PIANC (2001) to be used in performance based methods for seismic design of block type quay walls


Performance Examination of Two Seismic Strengthening Procedures by Pseudodynamic Testing
Kurt, Efe Gokce; Kurç, Özgür; Binici, Barış; Canbay, Erdem; Ozcebe, Guney (American Society of Civil Engineers (ASCE), 2012-01-01)
Pseudodynamic testing was employed to observe the seismic performance of two retrofit methods on two-story, three-bay frame structures. The test frames had hollow clay tile (HCT) infill in the central bay and incorporated the seismic deficiencies of Turkish construction practice, such as use of plain reinforcing bars, low-strength concrete, and insufficient confining steel. Two noninvasive and occupant-friendly retrofit schemes suggested in the Turkish Earthquake Code, namely, use of fiber-reinforced polyme...
Nonlinear analysis of R/C low-rise shear walls
Mansour, Mohamad Y.; Dicleli, Murat; Lee, Jung Yoon (SAGE Publications, 2004-08-01)
An analysis method for predicting the response of low-rise shear walls under both monotonic and cyclic loading is presented in this paper. The proposed analysis method is based on the softened truss model theory but utilizes newly proposed cyclic constitutive relationships for concrete and steel bars obtained from cyclic shear testing. The successfulness of the analysis method, when combined with new materials constitutive relationships, is checked against the test results of 33 low-rise shear walls reporte...
Investigation of the Applicability of AASHTO LRFD Live Load Distribution equations for Integral Bridge Substructures
Erhan, Semih; Dicleli, Murat (SAGE Publications, 2009-08-01)
In this study, applicability of the AASHTO LRFD girder live load distribution equations (LLDEs) for integral bridge (IB) abutments and piles is investigated. For this Purpose, numerous 3-D and corresponding 2-D structural models of typical IBs are built and analyzed under AASHTO LRFD live load. In the analyses, the effect of various superstructure properties such as span length, slab thickness, girder spacing and stiffness are considered. The results from the 2-D and 3-D analyses are then used to calculate ...
Analysis of the flexural strength of prestressed concrete flanged sections
Baran, Eray; French, Catherine (Precast/Prestressed Concrete Institute, 2005-01-01)
Inconsistencies in the sectional response of prestressed concrete flanged sections predicted by the AASHTO LRFD and AASHTO Standard Specifications, including the maximum reinforcement limits, may arise due to different interpretations of the equivalent rectangular compressive stress block idealization. Strain compatibility analyses with nonlinear material properties were performed for a variety of non-rectangular prestressed concrete sections to identify the inconsistencies between the two specifications. R...
Test method for determining the shear modulus of elastomeric bearings
Topkaya, Cem (American Society of Civil Engineers (ASCE), 2002-06-01)
The shear modulus of the elastomer is the most important material property related to the behavior of elastomeric bearings used principally at supports in bridges. Current methods for determining the shear modulus usually require small test samples cut from manufactured bearings. Such tests are costly, do not necessarily represent the performance of the full-size bearing, and are destructive. A new shear test method, called the inclined compression test, is reported that is nondestructive and only requires ...
