Abstract: The behavior of coupled-wall buildings primarily depends on the performance of coupling beams. Existing coupled-wall buildings designed and built prior to the 1970s contain coupling beams reinforced with horizontal and ...

Abstract: It is known that in well-operated anaerobic systems the majority of the residual chemical oxygen demand (COD) present in the effluent is due to soluble microbial products (SMP) generated during treatment. SMP production ...

Abstract: This paper investigates the effect of chelating agents on the bioavailability of Fe and Cu during anaerobic digestion. The results on metal speciation and methane production in anaerobic serum bottles showed that biomass ...

Abstract: epartures from axisymmetric balance dynamics are quantified during a case of secondary eyewall formation. The case occurred in a three-dimensional mesoscale convection-permitting numerical simulation of a tropical cyclone, ...

Abstract: he authors question the widely held view that radial contraction of a secondary eyewall during an eyewall replacement cycle is well understood and governed largely by the classical theory of axisymmetric balance dynamics. ...

Abstract: he authors conduct an analysis of the dynamics of secondary eyewall formation in two modeling frameworks to obtain a more complete understanding of the phenomenon. The first is a full-physics, three-dimensional mesoscale ...

Abstract: This paper presents test results of 18 small-scale reinforced concrete specimens of strengthened beams using carbon-fiber-reinforced polymer (CFRP) composites. The specimens were instrumented with strain gauges in a region ...

Abstract: This paper presents test results of six specimens representing older bridge columns with inadequate reinforcement detailing consisting of short lap splices at the base and widely spaced transverse reinforcement. Four of ...
