Gestión de la carga muerta con los materiales de construcción adecuados

Hay varios tipos diferentes de cargas que afectan a una estructura. Los requisitos del código de construcción se especifican en términos de cargas mínimas que una estructura debe poder soportar.

Generally speaking, residential and commercial buildings are designed for a variety of loads such as live load, snow load, wind load and seismic (earthquake) load in addition to having to support the self-weight of the structure (the dead load). 

Here we answer questions regarding dead load. 

What is the difference between dead load and live load?

Dead loads are the weight of the structure and the materials used to construct the building. This includes, among other things, the weight of the framing, sheathing, insulation and finish materials as well as the weight of permanent equipment such as roof-mounted HVAC units.

Live loads are the people and their belongings such as furniture and non-fixed (not permanent) appliances such as dishwashers or microwaves. Live loads are considered transient, meaning they can change based on the number of occupants, different furniture and the like, while dead loads are permanent.

So why do you need to calculate dead loads and live loads?

The building codes require that a structure be designed to support all the anticipated loads without collapse. While strength is the primary objective to support occupant safety, the codes also include requirements for serviceability-the conditions under which a building is still considered useful-to provide a level of adequate performance for the occupants. So when considering the dead load of building materials, it's the weight of those materials.

Is dead load for building materials the same as uniform load capacity?

Dead load for building materials is not the same as uniform load capacity. Uniform load capacity is the allowable load distributed across a whole region or element, such as a beam. The dead load of the building materials themselves is typically part of the uniform load capacity required. The dead load of the building materials, in other words, factors in the overall uniform load capacity. However, dead load can also be a discrete (point) load such as an HVAC unit mounted on a roof or a bracket supporting a water-filled sprinkler pipe.

Is dead load in residential construction a factor?

All loads, including dead loads, are important factors when designing any structure. For example, typical residential floor dead load ranges from 10 to 15 pounds per square foot (psf). However, heavier floor coverings such as tile can double the load or more.
