This paper presents results of testing eccentrically loaded columns externally wrapped with two types of materials. Six cylindrical (205 mm diameter and 925 mm height) plain columns were cast and tested. Half of the columns were wrapped with GFRP and the other half with CFRP. All columns were tested by applying an axial load at 50 mm eccentricity. In each group (GFRP or CFRP wrapped) of columns...

The correct determination of deformation capacity of a structural member will become more important in the future since nonlinear design methods will be used more often. This report deals with the examination of deformation capacity of the concrete compression zone. The influence of size and the effect of transversal reinforcement of prisms under eccentric compression on their deformation capac...

This paper summarizes the test results of an extensive research program sponsored by the US Transportation Research Board of the National Research Council to examine the behavior of high-strength concrete rectangular columns subjected to concentric and eccentric loading conditions. The variables considered in this investigation were concrete strength ranging from 7.9 ksi (55 MPa) to 16.5 ksi (1...

from the time that civil engineers have used steel in building structures, they tried to increase its strength so as to produce more economic and lighter structures by using more elegant sections. increase of steel strength is not always useful for all members of a steel structure. in some members under certain conditions, it is needed to reduce the strength as much as possible to improve the b...

INTRODUCTION: A long vascular pedicle is necessary for successful reconstruction of traumatic or diabetic feet. To obtain a longer vascular pedicle in perforator flaps, surgeons often use eccentrically rather than centrally located perforators.1-4 The aim of this study was to compare the safety and reliability of thoracodorsal artery perforator flaps harvested with centrally or eccentrically lo...

To reduce the global emission of CO2 from building industry, researchers, architects and manufacturers must consider new ways constructing precast concrete buildings. Modern columns walls are not optimized to applied load, there is potential save material. By creating a stronger column core lightweight cover, it possible carbon footprint. A method proposed calculate such eccentrically loaded tw...
