WebbAbstract In this dissertation, a new Prestressed Concrete-Steel Composite (PCSC) girder system is introduced. The PCSC girder is composed of a lightweight W-shape steel section with shear studs on its top and bottom flanges to achieve composite action with the pretensioned concrete bottom flange and the cast-in-place concrete deck. WebbNotably, the initial stiffness, yield load, and maximum load of D8 are generally higher, with lower ductility, compared to counterparts of S10, except for the initial stiffness of glubam. This finding suggests that the number of bolts have a strong influence on the observed mechanical properties more than the bolt diameter. 2.3.2. Cyclic loading
Webb2 maj 2011 · This means that all stiffnesses increase with pressure. Hence, all three input stiffnesses relate to a reference stress, usually taken as 100 kPa (1 Bar). Besides the model parameters mentioned above, initial soil conditions, such as preconsolidation, play an essential role in most soil deformation problems. WebbIn each iteration the geometrically linear stiffness matrix is augmented with an initial displacement stiffness due to the deformation in the last iteration and with an initial stress stiffness due to the last iteration's stresses [ 74 ].
WebbAn initial elastic stiffness of K = 10 5 GPa/m was used to ensure the displacement continuity at the interface in the absence of damage. The initial linear response is …
