How do you calculate seismic weight of a building?
The seismic load is calculated by taking the Total Seismic Weight and converting it into a horizontal direction by multiplying by the seismic response coefficient Cs. The program will apply a Diaphragm Surface load which represents the seismic contribution of the Slab weight and any additional Dyn Load.
What is seismic load on building?
Seismic loading is one of the basic concepts of earthquake engineering which means application of an earthquake-generated agitation to a structure. It happens at contact surfaces of a structure either with the ground, or with adjacent structures, or with gravity waves from tsunami.
What are the various methods of seismic analysis of buildings?
Three basic methods are available for analyzing the responses of a structure subjected to seismic ground wave: Static analysis. Response spectra analysis. Time history analysis.
What is seismic load analysis?
Seismic analysis is a subset of structural analysis and is the calculation of the response of a building (or nonbuilding) structure to earthquakes. It later became clear that the dynamic properties of the structure affected the loads generated during an earthquake.
Is seismic load a lateral load?
Seismic Loads as Lateral Loads Movement of any plate over other causes vibration and as a result it becomes an earthquake.
Does seismic weight include live load?
11) Effective Seismic Weight Except for as mentioned below, live load is not included in the inertial force; however, the seismic force is later combined with dead and live loads in the load combinations. [12.7.
How do you calculate total building weight?
How to Load Calculation Column Beam Wall Slab
- Volume of Concrete = 0.23 x 0.60 x 3 =0.414m³
- Weight of Concrete = 0.414 x 2400 = 993.6 kg.
- Weight of Steel (1\%) in Concrete = 0.414x 0.01 x 8000 = 33 kg.
- Total Weight of Column = 994 + 33 = 1026 kg = 10KN.
What is is code for seismic load?
The Indian seismic code IS 1893 has now been split into a number of parts and the first part containing general provisions and those pertaining to buildings has been released in 2002. The first Indian seismic code (IS 1893) was published in 1962 and it has since been revised in 1966, 1970, 1975 and 19841.
What are the basic assumption during an equivalent static load analysis of seismic load?
Equivalent static lateral force analysis is based on the following assumptions, 1) Assume that structure is rigid. 2) Assume perfect fixity between structure and foundation. 4)Dominant effect of earthquake is equivalent to horizontal force of varying magnitude over the height.
What are the parameters of seismic loads?
The following seismic parameters are considered: peak ground acceleration (PGA); peak ground velocity (PGV); the ratio PGA/PGV; Arias’ intensity ( ); root mean square acceleration (RMSa); the strong motion duration of Trifunac/Brady ( ); seismic power ( ); the spectral intensities of Housner (SIH), Kappos (SIK), and …
What is Overstrength factor in seismic design?
The overstrength, which is specified as member or structural capacity, is usually defined using overstrength factor, which may be defined as the ratio of maximum base shear in actuel behavior to first significant yield strength in structure.
