Some examples of random variables on real structures are material properties, loads and member dimensions.
It is assumed that all edge members of the octahedron have the same material properties and the members connecting the opposite vertices of the octahedron have different properties.
Rizkalla et al. (2009) conducted an experimental program to study material properties of PC members.
Following the same logic, the material properties of the members, central joint piece and adhesive are the same across the numerical models.
The dynamic impact process is influenced by many factors, including barge mass, impact velocity, oblique impact angle, water elevation, material properties of pier members, soil properties, etc.
The randomness of barge mass, impact velocity, oblique impact angle, water elevation, material properties of pier members and soil properties are considered.
Having parameters used as input nodes in ANN modeling such as dimensions of member, material properties of FRP and material properties of concrete, the target node was confined compressive strength for structural member.
The main reasons which are responsible for difference in experimental and numerical failure loads is mainly due to human error in experimental work, variation of material properties and stiffness of member.
After describing the material properties, mix designs and member details, the main observations from detailed measurements of the crack kinematics through a digital image correlation monitoring system, with focus on members developing shear-governed response, are reported.
