Design provisions for stair slabs in the Bangladesh Building Code
Kilic, H; Citipitioglu, E (1997-08-01)
This paper deals with the current state of the building code provisions for the structural design of concrete stair slabs in general and those proposed for the Bangladesh National Building Code (BNBC) in particular. The design of stairs has not received due attention in most building codes. As a result, stairs, as they occur with a variety of support conditions, are designed based on the individual designer's judgment. This results in considerable overdesign with some particular types of support arrangement...
Live Load Distribution Formulas for Single-Span Prestressed Concrete Integral Abutment Bridge Girders
Dicleli, Murat (American Society of Civil Engineers (ASCE), 2009-11-01)
In this study, live load distribution formulas for the girders of single-span integral abutment bridges (IABs) are developed. For this purpose, two and three dimensional finite-element models (FEMs) of several IABs are built and analyzed. In the analyses, the effects of various superstructure properties such as span length, number of design lanes, prestressed concrete girder size, and spacing as well as slab thickness are considered. The results from the analyses of two and three dimensional FEMs are then u...
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...
Seismic design of lifeline bridge using hybrid seismic isolation
Dicleli, Murat (American Society of Civil Engineers (ASCE), 2002-03-01)
This paper presents the merits of a hybrid seismic isolation system used for the seismic design of a major bridge. The bridge is analyzed for two different arrangements of seismic isolation systems. The first arrangement consists of friction pendulum bearings at all substructure locations; the other incorporates a hybrid system where laminated elastomeric bearings are used at the abutments and friction pendulum bearings at the piers. Analysis results have demonstrated that the hybrid seismic isolation syste...
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...
