Abstract: Behavior of short and deep beams made of concrete-filled fiber-reinforced polymer (FRP) tubes (CFFT) was compared experimentally to that of their slender counterparts. Ten specimens made from four types of glass FRP tubes ...

Abstract: This paper presents an innovative modular construction of bridge pier system with stay-in-place fiber reinforced polymer (FRP) forms filled with concrete. Two 1/6 scale precast modular frames were prepared of a prototype ...

Abstract: This paper reports on a feasibility study of splicing techniques for precast concrete-filled fiber-reinforced polymer (FRP) tubes (CFFT). A total of four spliced beams were tested. Three were internally spliced using grouted ...

Abstract: Field applications and laboratory research have shown the feasibility of concrete-filled fiber-reinforced polymer (FRP) tube (CFFT) in bridges. Yet, their widespread applications require developing appropriate design and ...

Abstract: To date, research on concrete-filled fiber-reinforced polymer (FRP) tubes (CFFT) has focused on the effect of static loads, simulated seismic loads, and long-term sustained loads. Dynamic fatigue behavior of CFFTs, on the ...

Abstract: A set of column-footing subassemblies were prepared to investigate construction feasibility and seismic performance of structural joints for concrete-filled fiber reinforced polymer (FRP) tubes (CFFT) as bridge substructure. ...

Abstract: A physics-based macroscopic global seismic damage model is developed for lattice shell structures excited by strong earthquakes. Global seismic damage is generated from so-called modal damage that is defined as the loss ...
