RISComparative Study of Seismic Behavior of Multistory Reinforced Concrete Framed Structures
Publisher: American Society of Civil Engineers
Abstract: A comparative study of the nonlinear behavior of reinforced concrete (RC) multistory structures is carried out on the basis of measured response of four six-story, three-bay framed structures, namely a regular bare frame, ...
Stiffness Characteristics of Composite Beams and Application in Damage Identification
Publisher: ASCE
Abstract: Composite structures are used commonly in civil engineering; a typical example is a bridge deck consisting of concrete slabs and steel girder beams, in which shear connectors are used to connect the concrete slabs and steel ...
Experimental Study of Crack Identification in Thick Beams with a Cracked Beam Element Model
Publisher: American Society of Civil Engineers
Abstract: Model-based crack identification in beam-like structures has been a classic problem. The authors have recently developed a framework to identify crack damage in beams based on a cracked beam element model, which stems from ...
Combined Continua and Lumped Parameter Modeling for Nonlinear Response of Structural Frames to Impulsive Ground Shock
Publisher: American Society of Civil Engineers
Abstract: The response of a beam-column frame to impulsive ground shock, such as those induced by an underground explosion, has characteristics of both impact and natural earthquake responses. The critical effects may be governed ...
Identification of Cracks in Box-Section Beams with a Cracked-Beam Element Model

Responses of Shallowly Buried Pipelines to Adjacent Deep Excavations in Shanghai Soft Ground
Publisher: American Society of Civil Engineers
Abstract: Analyses of well-documented field instrumentation data from two deep excavations in Shanghai soft ground indicate that displacements of shallowly buried pipelines caused by adjacent excavation are predominantly governed ...
Normal Instantaneous Squeeze Film Force for a Finite Length Cylinder
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A theoretical model for the normal instantaneous squeeze film force for a finite length cylinder is developed in this paper. The model assumes large unidirectional cylinder motion along a sleeve ...
A Nonlinear Model for Short Length, Cylindrical Squeeze Films With Large Planar Motions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A rotating shaft vibrating in a squeeze film bearing and a tube in a heat exchanger oscillating with fluid-filled cylindrical supports both involve cylindrical squeeze films. Many theoretical ...
Collapse-Resisting Mechanisms of Planar Trusses Following Sudden Member Loss
Publisher: American Society of Civil Engineers
Abstract: Progressive collapse incidents of truss structures are often reported; however, studies on the collapse resistance of truss structures are comparatively few. In order to investigate the collapse-resisting mechanisms of ...
Homogenization of Masonry Using Numerical Simulations
Publisher: American Society of Civil Engineers
Abstract: Homogenization is one of the most important steps in the numerical analysis of masonry structures where the continuum method is used. In the present study, equivalent elastic properties, strength envelope, and different ...
