Slenderness ratio effect on cracked beam

Journal of Sound and Vibration, 1992
Abstract It is well known that in vibrating cracked beams and shafts, coupling of bending and torsional vibration exists, due to the non-diagonal terms of the local compliance matrix. This phenomenon becomes more important as the slenderness ratio decreases.

Equivalent slenderness ratio for built-up members

Canadian Journal of Civil Engineering, 1993
Built-up struts that buckle about an axis perpendicular to the plane of the connectors should be treated as a "built-up" member as opposed to a "simple" member. This mode of buckling causes shear and moments in the connectors which deform the connectors.

Modified Slenderness Ratio for Built-up Members

Engineering Journal, 2007
Based on a review of theory, background for the historical development of the AISC specifications, and an updated experimental database, a simple model which maintains the accuracy for the calculation of the modified slenderness ratio of built-up members with closely spaced individual components (for example, double angles and double channels) that are

Bracket Loaded Webs with Low Slenderness Ratios

Engineering Journal, 1985
Welded bracket connections to the web of rolled sections are common connections. However, the AISC Manual of Steel Construction has no guidelines for estimating their capacity. Generally, the maximum load corresponds to the development of a two-dimensional yield mechanism in the web; but for sections whose webs have significant thickness relative to ...

Comparing Hysteretic Behavior of Flexible Piers with Different Stirrup Ratio and Slenderness Ratio

Advanced Materials Research, 2011
Flexible piers have been widely used in bridge engineering due to its superior ductility. The stirrup ratio and slenderness ratio were deemed to have a most important impact on hysteretic behavior of them. Five flexible piers were made under static vertical loads and low cyclic horizontal reversed loads.

Compressor efficiency with cylinder slenderness ratio of rotary compressor at various compression ratios

International Journal of Refrigeration, 2016
Abstract When the air conditioning and heating systems operate in low speed regions, the efficiency of inverter compressor is relatively low, owing to the reduction in motor efficiency. Nevertheless, the annual operating time of compressor is largely occupied by low speed regions.

Effect of Slenderness Ratio of the Specimen on Resonant Column Test Results

Journal of Testing and Evaluation, 2020
Abstract To investigate the effect of the slenderness ratio (L/d) of the specimen, resonant column (RC) tests were conducted on dry sand specimens by using three different values of L/d, namely 2, 3, and 4, keeping the same diameter (d = 50 mm) to measure the shear moduli and material damping associated with the shear strain varying ...

Local effective length factor in the equivalent slenderness ratio

Canadian Journal of Civil Engineering, 1995
The Canadian Standard S16.1 specifies an equivalent slenderness ratio to be used when determining the compressive resistance of a built-up member when buckling occurs about an axis perpendicular to the interconnectors. This equivalent slenderness ratio is the square root of the sum of the squares of the slenderness ratio of the built-up member acting ...

Effect of Slenderness Ratio on Free-to-Roll Wing Aerodynamics

Journal of Aircraft, 2011
M ANNED fighter aircraft and unmanned combat air vehicles may require high angle-of-attack maneuvers where the roll dynamics become crucial. Small unmanned air vehicles (UAVs) and fixed-wingmicro air vehicles often have separated flows [1,2]. These small vehicles fly at relatively high angles of attack and close to the stall conditions due to the poor ...

Calculation of Effective Lengths and Effective Slenderness Ratios of Stepped Columns

Engineering Journal, 1972
The analysis of stepped columns arises in the design of heavy mill buildings. Such columns are generally loaded at the top and at the section where the cross section changes. The application of the AISC Specification requires that the engineer determine the effective length of each section of the column.
