Sound insulation in multi-story timber buildings
During on an extensive investigation of a multi-story timber building with light-frame construction, several stages of the building process and their impact on sound transmission were observed. The sound insulation properties of the building components were measured before and while the buildings were occupied. Furthermore, interviews with the occupants were conducted. This procedure made it po...
متن کاملSeismic Design of Multi-story Buildings with Metallic Structural Fuses
Seismic design relies on inelastic deformations through hysteretic behavior. However, this translates into damage on structural elements, permanent system deformations following an earthquake, and possibly high cost for repairs. An alternative design approach is to concentrate damage on disposable and easy to repair structural elements (i.e., “structural fuses”), while the main structure is des...
متن کاملMostow Rigidity for Fuchsian Buildings
We show that if a homeomorphism between the ideal boundaries of two Fuchsian buildings preserves the combinatorial cross ratio almost everywhere, then it extends to an isomorphism between the Fuchsian buildings. It follows that Mostow rigidity holds for Fuchsian buildings: if a group acts properly and cocompactly on two Fuchsian buildings X and Y , then X and Y are equivariantly isomorphic. Mat...
متن کاملMarked Length Rigidity for Fuchsian Buildings
We consider finite 2-complexes X that arise as quotients of Fuchsian buildings by subgroups of the combinatorial automorphism group, which we assume act freely and cocompactly. We show that locally CAT(-1) metrics on X which are piecewise hyperbolic, and satisfy a natural non-singularity condition at vertices are marked length spectrum rigid within certain classes of negatively curved, piecewis...
متن کاملMitigation of Train-Induced Floor Vibrations in Multi-Story Buildings Using a Blocking Floor
A new method is developed for reducing train–induced floor vibrations in buildings. Vibration transmitted through building columns to the upper floors can be mitigated by considerably increasing the thickness of a lower floor, which is named the “blocking floor”. This can be a desirable and inexpensive solution for vibration mitigation. The work presented by this paper shows the ability of an i...
