What Are Lateral Loads?

In structural engineering, structures are made up of various types of supports that connect for the purpose of moving loads from the top to the bottom of buildings/structures.

Loads in any structure have to move from the top floor to the lower floor or ground floor. In engineering this action/ effect is called “load path” load paths must be continuous. For a load path to be stable, each consecutive member must support itself and the other members and loads that connect to it.

You can utilize a wind load calculator to determine the amount of force impacting a standing structure.

Lateral loads

Lateral load are load paths that have a comprehensive path to connect them to the ground. Unlike other types of load paths which acts in a downward direction (a.k.a gravity load), lateral loads act horizontally or instead can cause an uplift action.

Most typical lateral loads will be façade against a wind load, a pressure caused by earthquake against a beach front holding wall. Most lateral loads differ in strength depending on the structures’ physical setting, height, shape, and structural materials. The vigorous effects of earthquake and wind loads can be evaluated as corresponding fixed load in most mid-sized structures. For large structures, you must use the iterative capability of the computer.

The main types of lateral loads are the earthquake loads and wind loads.

Earthquake loads

These loads are very uncertain, more complex, and more damaging than wind loads. It is by luck they occur rarely. The earthquake triggers earth movements that can classified as “rattle” “shake” and “roll”. Every structure must be strong enough to cope with the three types of loads of different strengths. Although the ground at the base of the building might move in any direction, only horizontal mechanisms of this shift are deliberated to be serious in structural study. When it comes to analysis, it is assumed that a load-bearing construction that supports well calculated. It is also assumed that, design loads for perpendicular dead and live loads are sufficient for the vertical impact of the earthquake.

Wind loads

It the most common type of a lateral load, a good example is the Eiffel tower. Eiffel tower has a structure that was planned to resist a high intensity wind load. When high intensity wind blows a structure, a positive pressure is built on the windward side and pull on the leeward side.

Winds can cause loads of pressure on either direction. Thus, a planner must be aware of the dangers that may be caused by this type of lateral load. Factors that may affect the wind load include elevation, the geographical location, building size and height, direction of prevailing winds, degree of exposure, and negative and positive pressures depending on architectural designs.
