Composite limiting height data can be applied to walls where gypsum board is installed on both flanges of the stud for the full height of the wall Non-composite conditions are common in all structures When the gypsum board stops at the ceiling level but the stud continues to the deck it is a non-composite

Due to the common use of mechanical connections to join composite or hybrid structures the bearing performances of pin-loaded composite laminates have been widely analyzed in the last few years by several authors [5–8] In this context the kind of failure mechanism (i e bearing

A new hybrid composite beam (HCB) has recently been used in the construction of three bridges in Missouri USA HCB consists of self-consolidating concrete (SCC) that is poured into classical arch shape and tied at the ends by steel tendons Both the concrete and the steel are tucked inside a durable fiberglass shell and the voids are filled with polyiso foam

May 17 2020Crankpin overlap is a measurement of how much crankpin material is horizontally aligned with the material of the adjacent main journals as illustrated in Figure 8 showing a CPO of 0 225 with a 4 250 stroke crank having 2 100 rod journals and 2 600 main journals CPO has a direct relationship with both the stiffness (torsional and bending
