A high-ductility material or a high-ductility covering material is disposed on the outer circumferential surface of a member, such as a column, of a structure so as to confine expansion of apparent volume accompanying rupture of the member, to thereby control rupture of the member. The high-ductility material is a fibrous or rubber sheet material. The high-ductility material is disposed in such a manner as to surround the member. Alternatively, the high-ductility material is spirally wound or rolled on the member.

An aerodynamic ladder cover has been devised to provide an aerodynamic shape to the leading edges of a ladder while in transport. The cover includes a rigid curved forward-facing nosepiece. The nosepiece is substantially semi-cylindrical and its rigidity maintains a smooth-contoured convex surface facing the wind. In one embodiment of the invention, the rigid nosepiece is provided as an insert within layers of a soft cover overlying material. In this embodiment of the invention, the ladder cover is attached to the ladder by straps which extend from a back end of the cover. The construction of the ladder cover and straps permits the cover to be conveniently used as a contractor's tool bag.

A method for preparing or maintaining surfaces for construction-type work includes using at least one low-intensity infrared radiation heat source placed near the surface. The infrared radiation can warm the surface in preparation for the construction activity. Additionally, the radiation can be used to maintain the surface in a state that is conducive to construction activity. This type of treatment may be particularly useful in colder climates, where the weather affects the construction season.
