Naveed Anwar, Fawad Ahmed Najam, in Structural Cross Sections, 2017 Effect of Cross-Section Shape on Column Strength The following guidelines (not rules) may be used to choose the initial shape and dimensions of column cross-section: • Whenever practical, use square, rectangular, or circular...
Economical design of the column-foundation connections is difficult to achieve due to the complex structural details of the anchor frame in the foundation concrete following the arrangement of 2 or 3 lines of connections using anchors that are needed to deal with the enlargement of the constructions...
Although comprehensive researches have studied the structural behavior of RC circular columns under axial compression forces, the effect of edge moment (EM) transferred from beam–column joint with double curvature effect has yet to be investigated. The exposure to additional unexpected EM may result i...
eccDNA enriched was performed using the Phi29 enzyme5. Briefly, genomic DNA (2 μg) was first cleaned up using the PCR Cleanup kit (Qiagen) to remove large genomic fragments. The DNA on the column was eluted with 30 μL elution buffer. DNA concentration was measured with a Qubit flu...
Compared with circular columns, the design and fabrication of beam-to-column connections in polygonal columns are more convenient. In addition, the possibility of producing polygonal steel tubes by welding steel plates at the construction site makes transportation of structural members more convenient, ...
A set of column-footing subassemblies were prepared to investigate construction feasibility and seismic performance of structural joints for concrete-fille... Z Zhu,I Ahmad,A Mirmiran - 《Journal of Bridge Engineering》 被引量: 125发表: 2006年 Joint construction and seismic performance of concrete...
All fibers were wrapped manually around the column. The columns were tested at least 56 days after the specimen fabrication was completed. Fig. 4 Details of test specimens (Note: unit is in mm). Full size image All specimens were fabricated and tested at the Structural Laboratory of Hankyong...
Table 3 Set of the 8 transformations of the nucleotides forming the dihedral group\(D_8\). The first 4 transformations of the nucleotides form also the Klein V symmetry group. These are indicated as transformations in the rightmost column. ...
Concrete filled steel tubes are an economical column type, as the majority of the axial load is resisted by the concrete, which is less expensive than steel [3]. The steel tube serves as the formwork for casting the concrete, which reduces the construction cost. No other reinforcement is ...
Punching shear capacity could also be improved when concrete slabs were strengthened by four bonded post-tensioning strands in the inclined pre-drilled holes near the column [6]. The results indicated the punching shear capacity was improved as much as 51%, with the deformation being reduced by ...
