Abstract: For the Lehigh-Purdue concrete plasticity model, there seems to be certain limitations on the choice of material properties to ensure the convexity of the limiting surfaces describing the model. A set of inequalities is ...

Abstract: In this paper, a new general procedure is presented for modeling the effects of large displacements on the response of space frames subjected to conservative loading. An incremental definition of rotations is adopted based ...

Abstract: This paper presents the experimental results from a large research project dealing with the seismic behavior of semirigid steel frames. The investigation focuses on the performance of steel frames with semirigid connections ...

Abstract: This is the first of two papers addressing the efficient and simultaneously accurate analysis of reinforced concrete frames through the use of adaptive nonlinear analysis techniques. The present paper discusses the ...

Abstract: This is the second of two papers concerned with the application of adaptive techniques to the nonlinear analysis of reinforced concrete frames. The first paper presented a new nonlinear elastic formulation capable of ...

Abstract: The composite flexural action of prismatic reinforced concrete (RC) members repaired/strengthened by RC jacketing was modeled with a dual-section approach. The model considers the relative slip at the interface between the ...

Abstract: A methodology is developed in this paper for the design and proportioning of interventions for seismic upgrading of substandard reinforced-concrete (RC) buildings. The retrofit approach is presented in the form of a simple ...
