which consists of four automatics methods, i.e., rotation, alignment, bolting, and unloading, to place the steel beam and conduct temporary connection without a worker in high places. A prototype system was developed, and scaled tests were conducted in the laboratory to validate its feasibility....
Laser beam welding of open-porous metallic foams for application in cooling structures of combined cycle power plants J Eng Gas Turbines Power, 132 (May 2010) [9] A. Shirzadi, Y. Zhu, H. Bhadeshia Joining ceramics to metals using metallic foam Mater Sci Eng A, 496 (2008), pp. 501-50...
The different features that can be found at the SCI span over a large range of dimensions, i.e. from the nanometer scale (e.g. passive layer) to the order of centimeters or even decimeters (e.g. voids or honeycombs). The SCI properties continuously change as a function of time-...
and the effective depth of the beam; Mk is the ultimate moment, indicating the moment when the beam fails due to the yielding of the reinforcement, and is determined by considering the maximum distributed load on the beam, the span of the beam, and the effective depth of the beam; Eav ...
To model the members in nonlinear range of deformation, all frame members, i.e., beams, columns and braces, are assumed pin-ended. For modeling of braces, nonlinear beam and column elements with the material behavior of Steel01 are used. To simulate the buckling behavior of braces under ...
The effect of rubber replacing ratio (r) and shear span ratio (λ) were discussed. The main parameters of specimens are given in Table 1. The letter t represents the thickness of the tube; B is the side length of the specimens; L is the height of the specimens; Mue is the measured ...
The methods of a direct pull-out test and beam test are mainly used to measure the bond property [4]. By using the pull-out test, bond behaviors such as bond strength, slip and bond stress-slip relationship of ribbed steel bar in LAC have been studied. Zhang et al. [2] reported tha...
Figure 5 shows the step-by-step procedure of the SCS sandwich beam fabrication process. Concrete was cast into the skeleton of SCS sandwich beams. After the concrete had cured for 28 days, the specimens were ready. The geometric information for each specimen is listed in Table 2. Figure 4....
"I Lower Bound" and "I Constant Stiffness" are terms described in AISC 360. The 2D Sketch tab provides two ways to view a graphic representation of the beam currently being designed: Span & Loads tab: Cross Section tab: The Diagram tab offers the ability to view shear, moment, and ...
