Abstract: The free formulation of Bergan and Nygård (1984) has been successfully used in the construction of high-performance finite elements for linear and nonlinear structural analysis. In its original ...

Abstract: This paper is a tutorial exposition of the template approach to the construction of customized mass-stiffness pairs for selected applications in structural dynamics. The exposition focuses on adjusting the mass matrix while ...

Abstract: The cyclic behavior of welded beam-to-column joints for moment-resisting steel frames was assessed by constant amplitude cyclic quasi-static tests. Reanalysis of the results showed that the failure mode of the joints ...

Abstract: This note reports results of two tests performed on full-scale thin-walled prestressed concrete beams where the increase in external load is caused by changing the water level contained in the beam section. The purpose of ...

Abstract: We study three “incompressibility flavors” of linearly elastic anisotropic solids that exhibit volumetric constraints: isochoric, hydroisochoric, and rigidtropic. An isochoric material deforms without ...

Abstract: A numerical scheme for seismic analysis of nonhomogeneous embankment dam sections has been presented and shown to provide results that approximate reasonably well the more precise 2-D analyses in a gravel shell dam design. ...

Abstract: The equations of motion for an acoustic fluid enclosed in a moving or flexible container are studied. It is shown that the determination of the reference state must account for the ...

Abstract: This paper presents a formulation of the indirect boundary element method based on the principle of virtual work for the dynamic analysis of frame structures buried in semi-infinite elastic media. The present formulation, ...

Abstract: An approximate analysis of end supported, thin‐walled prismatic members of open profile section to predict buckling loads under dead weight and water loading is presented. When the critical buckling mode involves considerable ...

Abstract: This study presents experimental procedures conducted to characterize the bond between concrete and fiber reinforced polymeric laminates. The experimental characterization was aimed at obtaining the softening of the ...
