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...
متن کاملPunching strength of actual two-way slabs
Many building codes rely on empirical formulations with respect to the punching shear design provisions. Such empirical equations are typically calibrated on the basis of laboratory tests performed on simplified geometries (usually isolated specimens) with usually statically-determined loading conditions. On the contrary, actual structures, particularly two-way slabs, are continuous and highly ...

متن کاملEffect of Low Cycle Fatigue Predamage on Very High Cycle Fatigue Behavior of TC21 Titanium Alloy
The effect of low cycle fatigue (LCF) predamage on the subsequent very high cycle fatigue (VHCF) behavior is investigated in TC21 titanium alloy. LCF predamage is applied under 1.8% strain amplitude up to various fractions of the expected life and subsequent VHCF properties are determined using ultrasonic fatigue tests. Results show that 5% of predamage insignificantly affects the VHCF limit du...
متن کاملVibration fatigue in process pipework: A risk based assessment methodology
Risk Based Inspection (RBI) has been used for some time to optimise inspection schedules based on assessing the risk of various corrosion related degradation mechanisms. However, one degradation mechanism that has been traditionally overlooked is that of vibration induced fatigue. A proactive methodology for assessment of vibration induced fatigue was published in 2000 as part of a Joint Indust...
