What is meant by earthquake load?

What is meant by earthquake load?

The total force exerted on a structure by an earthquake.

What type of load is an earthquake?

The earthquake load is a ‘dynamic load’, which means it brings about the vibration of structures. Other loads such as dead, live, and snow loads generally act on structures very slowly and do not cause any rapid movement or vibration. These are called ‘static loads’.

What is an earthquake load in construction?

Seismic load indicates how much seismic energy (waves of energy that travel through the earth) a structure would need to endure in a specific geographic location.

How do you calculate earthquake loads?

An equation for the seismic load distribution, Ai =1/ αi , was obtained based on the assumption that the velocity spectrum of the ground motion is independent of the period. Further, it is obtained from the maximum shear response using the elastic shear bar with both uniform stiffness and mass distributions.

Is earthquake load a gravity load?

In the earlier stage of strong earthquakes, gravity load results in different plastic rotations and bending moments at both ends of beams in multistorey building structures. As a result, excessive structural damage may occur in the lower floors of multistorey building structures subjected to a strong earthquake.

What are the different types of load?

Different types of loads in buildings and structures

• Different types of loads. The loads in buildings and structures can be classified as vertical loads, horizontal loads and longitudinal loads.
• Dead load.
• Live load.
• Wind load.
• Snow load.
• Earthquake load.
• Load combination.
• Special loads.

What is load and its types?

The types of loads acting on structures for buildings and other structures can be broadly classified as vertical loads, horizontal loads and longitudinal loads. The vertical loads consist of dead load, live load and impact load. The horizontal loads comprises of wind load and earthquake load.

What is a construction load?

Construction loads include, but are not limited to, materials, personnel, and equipment imposed on the temporary or permanent structure during the construction process.

Is earthquake load a code?

Seismic requirements for Design, Detailing and Construction are covered in other codes, e.g., IS:4326, IS:13920, 3. For an Earthquake Resistant Structure, one has to follow IS:1893 (Part-1) together with Seismic Design and Detailing Codes.

What are the two types of load on a structure?

What are load combinations?

A load combination results when more than one load type acts on the structure. Building codes usually specify a variety of load combinations together with load factors (weightings) for each load type in order to ensure the safety of the structure under different maximum expected loading scenarios.

What are the 3 types of loads?

The types of loads that act on building structures and other structures can be broadly classified as vertical, horizontal, and longitudinal loads. Vertical loads consist of dead loads, live loads, and impact loads. Horizontal loads consist of wind loads and earthquakes.
