This study focuses on the propagation of harmonic mechanical waves around both circular
and non-circular tunnels. The excavation disturbed zone is explicitly modeled with a …

One of the most critical aspects in the design of tunnels or mine galleries is their support.
This one not only must be able to withstand the stresses to which it is subjected, but also that …

In this paper an optimization framework is presented for automated performance-based
seismic design of bridges consisting of multi-column RC pier substructures. The beneficial …

Composite RCS building frames integrate reinforced concrete columns with structural steel
beams to provide an efficient solution for the design and construction of earthquake-resisting …

In this paper, an optimization framework is developed for performance-based seismic design
of composite moment frames consisting of concrete filled steel box columns and I-shaped …

Concrete lining and rock bolts are usually provided to support excavated tunnels on different
ground conditions. These two support systems are worthy and need in-depth consideration …
