Dynamics of a Spring-Mass System The time interval required for the mass to complete one full cycle of motion is called the period of the vibration ? (in seconds) and is defined as: The frequency in hertz (Hz = 1/s) is f = 1/? = ? /(2?).

Natural Period Tn of a building is the time taken by it to undergo one complete cycle of oscillation. It is an inherent property of a building controlled by its mass m and stiffness k. These three quantities are related by its units are seconds (s).

The period is related to how stiff the system is. A very stiff object has a large force constant k, which causes the system to have a smaller period. For example, you can adjust a diving board's stiffness?the stiffer it is, the faster it vibrates, and the shorter its period.

Natural Period Tn of a building is the time taken by it to undergo one complete cycle of oscillation. It is an inherent property of a building controlled by its mass m and stiffness k. These three quantities are related by its units are seconds (s).

For seismic-resistant structures each structure has a unique natural or fundamental period of vibration, which is the time required for one cycle of free vibration. Parameters: The factors determining the fundamental period include structure stiffness and height.

ABSTRACT: Indian standard recommended that the natural time period is a function of Height of building and the Base dimension of the building. Here in this work, the attempt is to show that natural time period is also a function of number of storeys.

All buildings have a natural period, or resonance, which is the number of seconds it takes for the building to naturally vibrate back and forth. The ground also has a specific resonant frequency. Hard bedrock has higher frequencies softer sediments.

Natural vibration period of a building is affected by various parameters such as stiffness, mass, and their distribution in the structure, as well as height.

Natural Period Tn of a building is the time taken by it to undergo one complete cycle of oscillation. It is an inherent property of a building controlled by its mass m and stiffness k. These three quantities are related by its units are seconds (s).

The time period of undamped free vibration of structure is natural time period of that structure. The longest model time period of vibration is called fundamental time period.
