and findings of laboratory and field tests of a new generation of precast composite piles used for the first time in the construction of the Route 40 highway bridge over the Nottoway River in Virginia. The piles consisted of 24.6 in. (625 mm) diameter concrete-filled glass fiber reinforced polymer (GFRP) circular tubes, with a 0.21 in. (5.3 mm) wall thickness. The composite piles extended above...

This study investigates the mechanical behavior of steel fiber-reinforced concrete (SFRC) beams internally reinforced with steel bars and externally bonded with carbon fiber-reinforced polymer (CFRP) sheets fixed by adhesive and hybrid jointing techniques. In particular, attention is paid to the load resistance and failure modes of composite beams. The steel fibers were used to avoiding the rip...

This paper introduces a strengthening technique for steel monopole towers using high-modulus carbon fiber reinforced polymer (CFRP) materials. The technique is based on a theoretical and analytical investigation including testing large scale steel monopole towers strengthened with different CFRP materials and connection details. Based on the research findings, design aspects and installation pr...

Many gravity load designed (GLD) reinforced concrete (RC) frames are nowadays located in seismic areas. Different strengthening methodologies have been proposed in the past; an innovative technique based on the use of composites was proposed and validated by an experimental program developed at University of Missouri-Rolla. A theoretical approach for the assessment of the subassemblage capacity...

Introduction My initial appreciation of the role of the heart, in this instance the valves of the heart, in mental-emotional illness occurred in medical school, since in biomedicine at that time the prolapse of the mitral valve was associated with panic attacks and phobias. Therefore it was a simple cognitive step from that information to identifying other aspects of Heart function, the orifice...

Mr. Roach did his undergraduate civil engineering work under Prof. Hugh Miller, formerly of Clarkson College, now lecturer in civil engineering at Rice. When Mr. Roach graduated he went with the Public Service Commission of New York, and did surveying in connection with the new suburbs of New York City. On March 1, 1916, he accepted a position with the Turner Construction Company, engineers and...
