Buckling loads of columns of regular polygon cross-section with constant volume and clamped ends
A numerical method is developed for calculating the buckling loads of tapered columns of regular polygon cross-section with constant volume and both clamped ends. The linear, parabolic and sinusoidal tapers are considered in numerical examples. From the numerical results, the strongest columns by the taper types and side numbers of regular polygon cross-sections are identified.
متن کاملTests to investigate the web slenderness limits for cold-formed RHS in bending
Steel beam cross sections are normally classified according to the effect of local buckling on the moment capacity of the section. This is achieved by defining slenderness limits for the flange and the web. This paper describes a series of bending tests on cold-formed RHS to examine these limits. The resulting experimental relationship between web slenderness and plastic rotation capacity is gi...
متن کاملOn The Plastic Design Of Timber Beams With A Complex Cross-Section
For the design of steel and concrete structures, most modern international design codes allow the use of plastic stressstrain-diagrams for the analysis of the bending resistance of the cross-section in the ultimate limit state. Curiously, in Europe and most other parts of the world, timber structures are still designed for the ultimate limit state with the old, conservative concept of full elas...
متن کاملAn Upper Bound Solution for Analysis of Twist Extrusion Process with Elliptical Die Cross-section
Twist extrusion process is a rather new route to produce highly strained materials. In this process, severe plastic deformation is applied by large shear strains. In current article, required energy for twist extrusion by use of admissible velocity field together with the upper bound technique is predicted. The proposed model is capable of considering the effect of various parameters such as di...
متن کاملMonopole Antenna Radar Cross Section Reduction with Plasma Helix
In this paper, a new method for radar cross section reduction of a monopole antenna is proposed. In this method, a plasma helix like fluorescent bulbs is placed around the antenna element. The selected plasma parameter for this medium acts as an absorber without disturbing the antenna performance. The simulations show that radar cross section of simulated antenna is reduced in a wide frequency ...
