In building design, thermal mass is a property of the matter of a building that requires a flow of heat in order for it to change temperature. In scientific writing the term "heat capacity" is preferred. It is sometimes known as the thermal flywheel effect. [ 1] The thermal mass of heavy structural elements can be designed to work alongside a ...
The specific heat of the human body calculated from the measured values of individual tissues is 2.98 kJ · kg−1 · °C−1. This is 17% lower than the earlier wider used one based on non measured values of 3.47 kJ · kg−1· °C−1. The contribution of the muscle to the specific heat of the body is approximately 47%, and the contribution ...
Structural load. A structural load or structural action is a mechanical load (more generally a force) applied to structural elements. [ 1][ 2] A load causes stress, deformation, displacement or acceleration in a structure. Structural analysis, a discipline in engineering, analyzes the effects of loads on structures and structural elements.
Lumber is a sustainable and environmentally friendly construction material that could replace modern building materials (e.g. concrete and steel) given its structural performance, capacity to fixate CO 2 and low energy demand during the manufacturing process.
Medium-density fibreboard. Medium-density fibreboard ( MDF) is an engineered wood product made by breaking down hardwood or softwood residuals into wood fibre, often in a defibrator, combining it with wax and a resin binder, and forming it into panels by applying high temperature and pressure. [ 1] MDF is generally denser than plywood.
A sawmill ( saw mill, saw-mill) or lumber mill is a facility where logs are cut into lumber. Modern sawmills use a motorized saw to cut logs lengthwise to make long pieces, and crosswise to length depending on standard or custom sizes ( dimensional lumber ). The "portable" sawmill is simple to operate. The log lies flat on a steel bed, and the ...
Description. A load-bearing wall or bearing wall is a wall that is an active structural element of a building — that is, it bears the weight of the elements above said wall, resting upon it by conducting its weight to a foundation structure. [ 1] The materials most often used to construct load-bearing walls in large buildings are concrete ...
Parallel-strand lumber ( PSL) is a form of engineered wood made from parallel wood strands bonded together with adhesive. It is used for beams, headers, columns, and posts, among other uses. The strands in PSL are clipped veneer elements having a least dimension of not more than inch (6.4 mm) and an average length of at least 300 times this ...
