A method for seismic loss assessment including receiving by a computer system computer-readable input data regarding a seismic hazard and building conditions, generating by the computer system one or more mitigation options and for each of the mitigation options, configuring the computer system to: determine a structural response, determine damage states from the structural response, determine an outcome of each of the damage states; and, output a representation of each of the outcomes for each of the damage states. The output is used in a seismic risk mitigation plan and/or design for one or more building structures.

An energy dissipation device includes a primary core module, a housing module, first and second outer plates, an energy dissipation unit, first and second preload tension members and a resilient compression unit when the primary core module and the housing module are subjected to an external force, the first and second preload tension members stretched by the external force, and the resilient compression unit is compressed, such that relative movement between the primary core module and the housing module is generated. The energy dissipation unit generates a retarding force during the relative movement between the primary core module and the housing module, so as to dissipate the kinetic energy generated as a result of the external force.

A sliding seismic isolator includes a first plate attached to a building support, and an elongate element extending from the first plate. The seismic isolator also includes a second plate and a low-friction layer positioned between the first and second plates, the low-friction layer allowing the first and second plates to move freely relative to one another along a horizontal plane. The seismic isolator also includes a lower support member attached to the second plate, with a biasing arrangement, such as at least one spring member or at least one engineered elastomeric element, which can include one or more silicon inserts, positioned within the lower support member. The elongate element extends from the first plate at least partially into the lower support member and movement of the elongate element is influenced or controlled by the biasing arrangement.

A clip that fixes a ceiling joist intersecting a ceiling joist receiver to the ceiling joist receiver, includes: a top portion having a width of the ceiling joist receiver; a first hanging portion hanging down from one end of the top portion, and provided with, at a lower portion, first engaging projections extending left and right to engage the ceiling joist; and a second hanging portion hanging down from another end of the top portion, and provided with, at a lower portion, second engaging projections extending left and right to lock the ceiling joist. The first hanging portion has a length longer than that of the second hanging portion, and a recess extending in a direction toward the second hanging portion is provided at an intermediate position of the first hanging portion.

A brace assembly can include a structural member including a sidewall; and a bracket including a baseplate defining a slot extending from an open end to a closed end, the baseplate defining at least one baseplate hinge hole at the open end; a clamp including a jaw member and a tightening member, the jaw member and the tightening member engaging the sidewall to couple the structural member to the bracket, the jaw member defining a clamp hinge hole; and a hinge pin engaging the at least one baseplate hinge hole and the clamp hinge hole.

A seismic isolation structure using a rope foundation of the present invention is to separate and support an object from a ground at the same time. The seismic isolation structure may include a base positioned on the ground and provided with an accommodating space with an opened upper portion and two or more rope supporters spaced apart around an entrance of the accommodating space, a support including a stage for supporting an object, and a column protruding downward from the stage and positioned in the accommodation space, and ropes connecting the rope supporter and the lower part of the column to support the support to be spaced apart from the base.

This antivibration sound insulation device is provided with: an antivibration mechanism which is mounted on a stand and disposed close to a prescribed sound source at a plant; and sound-absorbing sound insulation walls which are supported by the antivibration mechanism and arranged so as to surround the sound source.
