EARTH QUAKE RESISTANT STRUCTURES ABSTRACT Earthquake is the shaking of the ground caused by the sudden breaking and shifting of large sections of Earth ’s rocky outer shell. Earthquakes are among the most powerful events on earth‚ and their results can be terrifying. Earthquakes in general does not kill people directly. Instead‚ many deaths and injuries result from the collapse of buildings‚ bridges‚ and other structures. We cannot prevent natural disasters from striking‚ but we can prevent

The Centennial Bridge was constructed to eliminate this bottleneck and reduce traffic congestion on the Bridge of the Americas. The bridge is a cantilever design where the suspended span is a tied arch. The bridge has a total length of 1‚654 m (5‚425 ft) in 14 spans‚ abutment to abutment. The main span measures 344 m (1‚128 ft) and the tied arch (the center part of the main span) is 259 m (850 ft)
