Abstract: The results from dynamic analyses by computer of an existing 13‐story steel moment resisting frame building are presented. The computed dynamic properties and response behaviors are compared to the true values as determined ...

Abstract: Control algorithms for rotor load mitigation are today generally adopted by industry. Most of them are based on the Coleman transformation, which is easy to implement and bears satisfactory results when the rotor is balanced. ...

Abstract: Anisotropic piezocomposite transducers (APTs), such as macro fiber composites and active fiber composites, have great potential to be used as structurally integrated transducers for guided-wave ...

Abstract: Clause 10.15.3 of the 1995 ACI code (ACI 318-95) defines the effective strength of a high-strength concrete interior column with an intervening normal strength concrete slab. This provision is based on laboratory tests in ...

Abstract: The two-dimensional steady-state Navier-Stokes equation and the continuity equation are applied to the lubricating film assumed to be concentric in journal bearings operating at very high speeds. ...

Abstract: A summary is given of the design, installation and performance of a system of submerged vanes (“Iowa Vanes”) for erosion protection in a bend of East Nishnabotna River, Iowa. The system functions by eliminating, or reducing, ...

Abstract: This study presents the results of one of the first attempts to characterize the pore water pressure response of soils subjected to dynamic loading under saturated and unsaturated conditions. The resilient modulus, which ...
