The basic assumption of the analysis of wall-frame structures is that two dissimilar structural systems, deforming in shear and flexural modes, are constrained to act together. The same set of boundary conditions is also assumed to be applicable to both types of components. An inconsistency arises when the rotation at the lower end of the combined beam is assumed to be zero because this boundary condition is applicable only to the flexural component of deformation. For the shear component that is related to the slope of the elastic curve to calculate the force, this assumption results in zero base shear force. In this study, a modified theory is developed on the premise that a frame-wall system can be separated into two substructures that lie above and below the point of counter-flexure in the base story columns. Except for a modification to include the effects of link beams, the generalized continuum approach is employed to derive the governing differential equation of the upper substructure. The bottom substructure is used to transmit the applied base boundary conditions to the continuum model, thus allowing a more accurate shear force calculation for each of the components. Comparisons of results calculated from this artifice with other formulations prove the superiority of the proposed improvement. Copyright (c) 2010 John Wiley & Sons, Ltd.

A simplified non-linear procedure for buildings with shear walls
TEKELİ, Hamide; Atimtay, Ergin (Thomas Telford Ltd., 2015-01-01)
A simple and easily applicable analytical method is proposed to obtain the capacity curve of buildings with shear walls as the first stage of a seismic pushover analysis. The method is based on controlling the curvature distribution of shear walls. Accuracy of the method was examined based on data of three sample buildings compiled from the literature. The buildings have different floor areas, number of storeys and cross-sectional areas of shear walls. The method can be economically used with respect to bot...
Analytical prediction of thermal displacement capacity of integral bridges built on sand
Dicleli, Murat (SAGE Publications, 2005-02-01)
In this research, analytical equations are developed to calculate the lateral displacement capacity and maximum length limits of integral bridges built on sand based on the low-cycle fatigue performance of the piles under cyclic thermal variations and the ultimate strength of the abutment under positive thermal variations. To formulate the displacement capacity and maximum length limits of integral bridges based on the low cycle fatigue performance of steel H-piles under cyclic thermal variations, first, H-...
A RANDOM-FIELD MODEL FOR THE ESTIMATION OF SEISMIC HAZARD
Yücemen, Mehmet Semih (Elsevier BV, 1993-10-01)
A stochastic framework is developed, in terms of the theory of homogeneous random functions, to estimate the seismic hazard associated with linearly extending seismic sources. The formulation is carried out in the space-time domain. An earthquake having at least a magnitude of m is assumed to occur whenever the total strain energy accumulated over the potential rupture plane exceeds the energy level corresponding to this magnitude, m. An alternative formulation, in which an earthquake is generated when the ...
A comparative study on different analysis approaches for estimating the axial loads on columns and structural walls at tall buildings
Kurç, Özgür (Wiley, 2013-04-01)
Estimating axial loads on columns and structural walls at tall buildings is a complicated task because time-dependent deformations of concrete and the way the building is constructed affect the way the gravity loads are carried by them. The accurate computation of axial loads is crucial for determining the size and strengths of columns and structural walls. This study investigates several analysis approaches commonly used during the design of such buildings. Construction sequences, time-dependent deformatio...
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...
