Structure Period Document For Free

An integral part of building codes in the United States, ASCE/SEI 7, Minimum Design Loads and Associated Criteria for Buildings and Other Structures describes the means for determining design loads including dead, live, soil, flood, tsunami, snow, rain, atmospheric ice, seismic, and wind loads and their combinations ...

This is the PERIOD of the building AND it IS DEPENDENT ON HEIGHT. TALLER BUILDINGS MOVE with Longer periods. They sway for a Long time. SHORTER BUILDINGS MOVE with Shorter periods.

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.

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.

The natural frequency of buildings depends on its mass and structural characteristics. As a rule of thumb, we can say with 10 floors, the time period of a building would increase by 1 sec. This means a 30-storey building would have a time period of 3 seconds i.e a natural frequency of 1/3=0.33 hz.

This property (time period) is dependent on factors such as mass, stiffness and the strength of the structure. Time period is also affected by several factors such as section dimensions, number of storeys, number of bays, loading, structural regularity, reinforcement, etc.

The natural period of a building is simply a time taken by it to undergo one complete cycle of oscillation. The natural period is one of the properties or building which is controlled by mass and stiffness.
