Introduction

When designing and constructing a structure or building, it is essential to consider the various loads that will act upon it. Understanding these loads is crucial for ensuring the structural integrity and safety of the construction.

Dead Loads

Dead loads refer to the permanent and stationary loads that act continuously on a structure. These loads are primarily caused by the weight of the building materials, such as walls, floors, roofs, and permanent fixtures.

Examples : Examples of dead loads include the weight of concrete slabs, beams, columns, walls, and the permanent fixtures like HVAC systems, plumbing, and electrical installations. These loads remain relatively constant throughout the structure's lifespan.

Live Loads

Live loads, also known as imposed loads, are temporary loads that can change in magnitude and location. They result from the occupancy and use of the building, including the weight of people, furniture, equipment, and movable partitions.

Examples: Live loads can vary depending on the purpose of the building. In residential buildings, they include the weight of occupants, furniture, appliances, and storage. In commercial buildings, live loads can include the weight of office equipment, merchandise, and the additional weight caused by crowds in public areas.

Snow Loads

Snow loads are the loads exerted on a structure due to the accumulation of snow on its surfaces, including roofs, walls, and other horizontal surfaces. These loads can vary depending on the geographic location and the snowfall patterns in the area.

Examples: Snow loads are prevalent in regions that experience heavy snowfall. The weight of the accumulated snow can exert significant pressure on the roof, potentially leading to structural failures if not properly considered in the design. Snow loads also need to be considered for other horizontal surfaces, such as decks and balconies.
