the collector (or membrane), used as a shear panel to carry in-plane shear; The drag strut member, used to transfer the load to the shear walls or frames; the chord, used to resist the tension and compression forces that develop in the diaphragm since the collector is usually incapable of handling these loads alone
A typical timber shear wall consists of braced panels in the wall line, constructed using structural plywood sheathing, specific nailing at the edges, and supporting framing. A shear wall is an element of a structurally engineered system that is designed to resist in- plane lateral forces, typically wind and seismic loads.
This low wall structure itself may fail in shear or in its connections to itself at the corners, leading to the building moving diagonally and collapsing the low walls. The likelihood of failure of the pin-up can be reduced by ensuring that the corners are well reinforced in shear and that the shear panels are well connected to each other ...
Dry-stone walls of Machu Picchu Temple of the Sun, Peru. Peru is a highly seismic land; for centuries the dry-stone construction proved to be more earthquake-resistant than using mortar. People of Inca civilization were masters of the polished 'dry-stone walls', called ashlar, where blocks of stone were cut to fit together tightly without any ...
EN 1998-1 applies to the design of buildings and civil engineering works in seismic regions. It is subdivided in 10 Sections, some of which are specifically devoted to the design of buildings. Section 1 of EN 1998-1 contains the scope, normative references, assumptions, principles and application rules, terms and definitions, symbols and units.
Spiraling disorder and crime surrounding a controversial safe injection site in East Harlem has residents now begging the Trump administration to intervene and quell their daily turmoil.
