Punching shear design with control perimeters subjected to asymmetrical bending

Strength of Footing with Punching Shear Preventers

The punching shear failure often governs the strength of the footing-to-column connection. The punching shear failure is an undesirable failure mode, since it results in a brittle failure of the footing. In this study, a new method to increase the strength and ductility of the footing was proposed by inserting the punching shear preventers (PSPs) into the footing. The validation and effectivene...

Meniscal shear stress for punching.

AIM Experimental determination of the shear stress for punching meniscal tissue. METHODS Meniscectomy (surgical treatment of a lesion of one of the menisci) is the most frequently performed arthroscopic procedure. The performance of a meniscectomy is not optimal with the currently available instruments. To design new instruments, the punching force of meniscal tissue is an important parameter...

Background to the Model Code 2010 Shear Provisions - Part II Punching Shear

This paper outlines the theoretical background of the punching shear provisions implemented in the fib Model Code 2010 and presents a practical example of its application. It is the aim to explain the mechanical model that forms the basis of the punching design equations, to justify the relevance of the provisions and to show their suitability for the design and assessment of structures. © 2013...

Moisture Content - Strength Relationship for Lumber Subjected to Bending *

Kennedy (1965) reported small clear strength values for most Canadian species. The average value for modulus of rupture for Douglas Fir based upon 1057 specimens was reported to be 7540 p. s. (52 026 kN/m2 ) when tested in the green (wet) condition while the average value for air-dried specimens adjusted to 12% moisture content was found to be 12,850 p.s.i. (88 665 kN/m2 ), an increase of 71%. ...
