HP and DR of Structures
The table below gives DR and HP for some common objects. All of these structures are Homogenous (see Injury to Unliving, Homogenous, and Diffuse Targets). For the effects of damage, see Damage to Buildings and Structures. Assume a structure in good repair has HT 12, should this become important (e.g., when rolling to see if a rope snaps under stress).
DR: The structure's Damage Resistance.
HP: The structure's Hit Points. Optionally, this can be calculated for buildings: HP = 100 × (cube root of building’s empty weight in tons), and typical weights per 1,000 square feet (sf) of area are 50 tons for wood frame or mud brick, 100 tons for steel frame or brick, and 150 tons for stone.
Notes: "No Crushing" indicates a structure so resilient that crushing damage cannot destroy it. Structures marked "Combustible" or "Brittle" are Fragile.

* Repeated impaling, piercing, and large piercing attacks against the same small spot (an area with SM 0 or less) lower DR at that specific point as if it were semi-ablative; repeated burning, corrosion, crushing, cutting, or huge piercing attacks at that same spot reduce DR at that point as if it were ablative. DR never falls below 1 for wood or 3 for brick, concrete, or stone. For rules governing semi-ablative and ablative DR, see the Damage Resistance advantage.
