WebNov 10, 2016 · The aforementioned seismic measures are used to calculate forces that earthquakes impose on buildings. Ground shaking (pushing back and forth, sideways, up and down) generates internal forces within buildings called the Inertial Force (FInertial ), which in turn causes most seismic damage. FInertial = Mass (M) X Acceleration (A). WebDec 23, 2024 · Based on the seismic design code, the range of the maximum story drift ratio of a multi-story R.C. structure under different seismic fortification levels is obtained, as shown in Table 1. Parameters in this table are used to evaluate the structural seismic capacity for different seismic fortification levels in this paper.
WebThis study aims to make clear the constitutive relations, capacity gradients and probability assurance of beam-column joints following Chinese seismic code based on pseudo-static tests. Twelve joint specimens are made in 1:1.5 large scale and grouped by fortification levels, exterior - interior locations, and middle – bottom stories.
