ANALYSIS OF FRAME-CORE WALL BUILDINGS CONSIDERING EFFECTS OF AXIAL FORCE AND AXIAL DEFORMATION
… are replaced by continua with equivalent shear rigidity, GA, and flexural stiffness, EIa. The effect of axial force is included in the derivation of shear stiffness. Charts are presented to facilitate the determination of shear rigidity for different levels of axial force ratio, P / Pcr , in …

Numerical Modeling and Analysis of Composite Beam Structures Subjected to Torsional Loading
… equivalent homogeneous material, the effective torsional rigidity of the laminated composite rods can be determined by employing the theory developed by Lekhnitskii in 1963. Finally, the predicted results based on the present analytical approach are compared with those by the finite element, the …

Aeroelastic behaviour of composite wings
… methods for the determination of cross-sectional rigidity properties follows for beams constructed of laminated and thin-walled materials. Chordwise stiffness is shown to be an important parameter that must be considered as it has a significant effect on the amount of bending-torsion coupling …

Cis and Trans, p53 and NF-kB rules of transactivation
… nucleotides flanking an RE, selected based on torsional flexibility measurements. For the NF-kB family, relA/p65 and NFkB1/p50 were tested as single proteins or when co-expressed using a panel of REs selected based on different DNA binding affinities. The correlation between DNA binding and …

Multiscale Structures and Mechanics of Biomineralized Lattices in Hexactinellid sponges and Echinoderms
… are found to provide tendency to optimize torsional rigidity, and enhanced radial stiffening and improved permeability, respectively. The cellular structure in the spine of the H. mammillatus (i.e., stereom) made of ~99wt% of single-crystalline calcite shows a multiscale functionally graded …

Lateral-Torsional Buckling Instability Caused by Individuals Walking on Wood Composite I-Joists
… have poor resistance to applied lateral and torsional loads and are susceptible to lateral-torsional buckling instability. Workers walking on unbraced or partially braced wood I-joists can induce axial and lateral forces as well as twist. Experimental testing demonstrated that workers cause …
