Get PriceEarthquake engineering is an interdisciplinary branch of engineering that designs and analyzes structures, such as buildings and bridges, with earthquakes in mind. Its overall goal is to make such structures more resistant to earthquakes. An earthquake (or seismic) engineer aims to construct structures that will not be damaged in minor shaking and will avoid serious damage .

Get PriceThe table dimensions that consist of the fixed bottom plane are 1000 mm x1300 mm. Both axes have a displacement capability of ±150 mm. A total of 4 limit switches are installed to ensure the table's safety against the possibility of exceeding the maximum displacement limits in the xand ydirections. The table movement is automatically stopped

Get Price· If they were inside the table legs the tables would be set to a fix point. As it stands you have created a flex point and it will loosen over time. You can keep the design aspects the same. But simply adding a 34 inch piece (4 pieces total) right under the top and in between each leg will really change the performance.
