As a new alternative design, plate-reinforced composite (PRC) coupling beam achieves enhanced strength and ductility by embedding a vertical steel plate into a conventionally reinforced concrete (RC) coupling beam. Based on a nonlinear finite element model developed in the authors' previous study, a parametric study presented in this paper has been carried out to investigate the influence of se...

In this work, changes undergone at the passive layer of a new type of corrugated austenitic stainless steel (low Ni, high Mn 204Cu type) when exposed to solutions simulating that contained in the pores of concrete have been studied. Changes in the nature of the passive layer have been characterized by X-ray photoelectronic spectroscopy (XPS) and electrochemical impedance spectroscopy (EIS). Par...

We consider the use of a dielectric-loaded structure to extract rf energy from a high current electron drive beam as a power source for a high energy two-beam accelerator. This represents an alternative technique which we show to have some significant advantages over the use of the currently proposed corrugated metal structures as power extraction devices. We discuss a particular design that wi...

In order to accurately calculate the cross-sectional stresses and deflections of improved composite box girder with corrugated steel webs, control differential equations boundary conditions are established based on energy variational principle, taking into account effects web properties, shear lag, deformation. A cantilever is used as a numerical example. The influence width span ratio bending ...

This paper describes the prototype design, specimen design, experimental set-up, and experimental results of tests on three light-gauge steel plate shear wall (SPSW) concepts. Prototype light-gauge steel plate shear walls are designed as seismic retrofits for a hospital structure in an area of high seismicity and emphasis is placed on minimizing their impact on the existing framing. Three singl...

This paper reports on the following: (1) Simple experimental investigations of pultruded fiber-reinforced plastic (PFRP) material behavior and tests of simple epoxied joints to verify and enhance the reported database; (2) cyclic tests of an attempted PFRP rigid beam-column connections; and (3) preliminary observations regarding the seismic-resistance worthiness of PFRP structures. These are si...

Steel plate shear walls (SPSWs) offer good energy dissipation capability when subjected to seismic forces as a robust lateral load resisting structure. This research investigated the cyclic behaviors of innovative infill web-strips (IWS-SPSW) and conventional unstiffened steel (USPSW) experimentally numerically. As result, two specimens 1:3 scale three-story single-bay IWS-SPSW USPSW were fabri...
