Location Building Detail Fields

The following table describes the Touchstone location fields related to the secondary building characteristics (that is, the building detail) of this location:

AIR's individual risk methodology follows a structured, logical approach that groups building characteristics according to their function to reflect the contribution of each characteristic to overall building performance. For information about the secondary risk characteristics that are supported in a specific model, refer to the "Model in Touchstone” chapter in the model description, which is available on AIR's Client Portal. Documentation for some AIR models includes a separate document that serves as a guide to the secondary risk characteristics (SRC) used in the model.

Building Condition

       CA EQ

       HI EQ

       HI TC

       JP EQ

       US EQ

       US HU

       US ST - Straight-Line Winds, Tornados

       NZ EQ

One of the following general qualitative descriptions of the condition of the building at this location, based on visual inspection of the building cladding and maintenance:

       Unknown (0)

       Average/default (1)

       Good (2)

       Poor (3)

The external appearance of cladding and maintenance gives a qualitative estimate of expected performance.

For earthquakes: Buildings with signs of distress or duress, such as cracking due to aging and ground settlement or overloading or cracking due to damage from previous earthquakes, are likely to experience additional damage during an earthquake.

For hurricanes: Buildings with signs of distress or duress are likely to experience additional damage during a tropical cyclone. Some examples of these signs are an aging roof, exterior walls, or cladding; loose roof tiles or chimney damage; or damage from previous tropical cyclones.

       Optional

       Defaults to a value in the Touchstone user interface

Unknown/default (0)

Building Shape

       CA EQ

       HI EQ

       JP EQ

       US EQ

       NZ EQ

One of the following values to describe the overall shape of the footprint of the building at this location:

       Unknown/default (0)

       Square (1)

       Rectangle (2)

       Circular (3)

       L-shaped (4)

       T-shaped (5)

       U-shaped (6)

       H-shaped (7)

       Complex (8)

Shape is critical for the performance of a structure, especially for large commercial buildings. In general, simple regular forms, like squares and rectangles, perform better than combinations of those, such as L- and T-shaped buildings. The sharp corners in these complex shapes are vulnerable.

       Optional

       Defaults to a value in the Touchstone user interface

Unknown/default (0)

Torsion

       CA EQ

       HI EQ

       JP EQ

       US EQ

       NZ EQ

One of the following values to describe the layout of structural elements that can lead to torsional loads in the building at this location:

       Unknown/default (0)

       Symmetric (1)

       Asymmetric (2)

       Corner building (3)

Wedge-shaped buildings and corner buildings are typical examples in which the lateral load-resisting components in a building are placed asymmetrically. This leads to torsional forces being induced when the building is shaken, which can lead to significant damage.

       Optional

       Defaults to a value in the Touchstone user interface

Unknown/default (0)

Soft Story

       CA EQ

       HI EQ

       JP EQ

       US EQ

       NZ EQ

One of the following values to indicate whether there is structural weakness at any floor in the building at this location:

       Unknown/default (0)

       No (1)

       Yes (2)

This field is only applicable if the number of stories is 2 or greater.

First-floor garages and taller first floors are likely to exhibit soft-story behavior.

The weakness is usually in the lateral load-resisting capacity of the floor and can often result in total (pancaking) collapse of the floor. In residential buildings, it is most often found in the first floor due to large openings or garages. In multi-story buildings, it can be present at any floor, although a large number of case histories exist with collapse of the first floor.

       Optional

       Defaults to a value in the Touchstone user interface

Unknown/default (0)

Structural Irregularity

       CA EQ

       HI EQ

       JP EQ

       US EQ

One of the following values to describe irregularity in such things as floor plans, structural components, uneven weight distribution, etc. for the building at this location:

       Unknown/default (0)

       Vertical Offset (2)

       Non-uniform Floor Area (3) (e.g., a sudden change in floor area along the height)

       Discontinuous Shear Wall (4) (i.e., the main load-resisting components are not provided in a regular, symmetric pattern)

       Heavy floor (5) (e.g., placement of heavy equipment on higher floors)

AIR no longer supports the Regular (1) value. If you use this value, Touchstone maps it to Unknown/default (0) upon import.

Structural irregularities can lead to catastrophic collapse of properties as witnessed in the Mexico City and Kobe earthquakes.

       Bracing of soft-story (3)

       Foundation anchorage (bolting) (4)

       Glass/window strengthening (5)

       Tilt Up (6)

       General (7)

A properly retrofitted structure can resist earthquakes even though the original structural form had weaknesses.

       Optional

       For U.S. Earthquake (M11), if you want to use the Bracing of cripple walls (1) option, you must also select Crawlspace cripple wall (4) as the foundation type.

       For U.S. Earthquake (M11), if you want to use the Foundation anchorage (bolting) (4) option, you must also select Gravity/Friction (4) as the foundation connection.

       CA EQ

       HI EQ

       JP EQ

       US EQ

One of the following values to indicate whether there are short columns in the building at this location:

       Unknown/default (0)

       No (1)

       Yes (2)

This field applies to old concrete structures in which the fill height of some columns has been restricted by spandrel beams or infill walls. If some of the columns along the perimeter are shorter than the adjacent columns, there is high chance that the shorter columns can no longer bear the loads for which they were originally designed.

Optional

 

Ornamentation

       CA EQ

       HI EQ

       JP EQ

       US EQ

One of the following values to describe the amount of decorative elements attached to exterior of the building at this location:

       Unknown (0)

       None/default (1)

       Average (2)

       Extensive (3)

Decorative elements may fall during an earthquake. Examples include unreinforced or unbraced parapet walls or entryway roofs, which can break off during excessive shaking.

Optional

 

Water Heater

This field is reserved for future use in the Japan Earthquake model.

       CA EQ

       HI EQ

       JP EQ

       US EQ

One of the following values to indicate whether the water heater in the building at this location is braced:

       Unknown/default (0)

       Braced (1)

       Unbraced (2)

If the water heater in a residential building is not properly secured, it can topple during earthquakes and cause damage, to both itself and any part of the structure underneath it.

Optional

 

Redundancy

       CA EQ

       HI EQ

       JP EQ

       US EQ

One of the following values to indicate whether there are multiple lateral load-resisting elements (frames or shear walls) in the building at this location:

       Unknown/default (0)

       No (1)

Redundancy provides additional reinforcement against earthquake damage.

Optional

 

Tall One Story

       CA EQ

       HI EQ

       JP EQ

       US EQ

One of the following values to describe the height of the one-story building at this location:

       Unknown/default (0)

       <= 20 feet (1)

       > 20-40 feet (2)

       > 40 feet (3)

Single story buildings that are taller than typical one-story structures (e.g., churches, gymnasiums, auditoriums, etc.) have been observed to experience more damage. The majority of the seismic weight of the building (the building's roof) is further from the ground, which may induce larger overturning forces. The structure may also contain slender elements that may be more likely to experience buckling failure modes.

Optional

 

Equipment

       CA EQ

       HI EQ

       JP EQ

       US EQ

One of the following values to describe the level of equipment bracing in the building at this location:

       Well-braced (1)

       Average-braced/default (2)

       Unbraced (3)

Anchoring mechanical and electrical equipment to the floor or bracing them against structural elements can resist damage. Vibration isolators (springs) are not as effective. In addition, piping should be braced to restrain the movement.

Optional

 

Seal Of Approval

       HI TC

       US HU

       US ST - Straight-Line Winds, Tornados

One of the following values to describe the level of professional engineering attention given to the design of the structure of the building at this location The following list describes each value (in bold):
