During the working operation the staff of the warehouse found that there is various uneven settlements was occurring the existing flooring. M\/s O.B Developers (Structure Audit Agency) was requested to check the maximum load carrying capacity of the floor and in case the floor capacity is found less than 700Kg\/sqm a methodology will be suggested to increase the floor load carrying capacity.<\/p>\n\n\n\n<ol class=\"wp-block-list\" type=\"1\"><li><strong>&nbsp; <u>What is Plate Load Test<\/u><\/strong><\/li><\/ol>\n\n\n\n<p>The plate load test&nbsp;is a field test, which is performed to determine the ultimate bearing capacity of the soil and the probable settlement under a given load. This test is very popular for the selection and design of the shallow foundation.<\/p>\n\n\n\n<p>For performing this test, the plate is placed at the desired depth, then the load is applied gradually and the settlement for each increment of the load is recorded. At one point a settlement occurs at a rapid rate, the total load up to that point is calculated and divided by the area of the plate to determine the&nbsp;<strong>ultimate bearing capacity<\/strong>&nbsp;of soil at that depth. The ultimate bearing capacity is then divided by a factor of safety (typically 2.5 to3) to determine the&nbsp;<strong>safe bearing capacity<\/strong>.<\/p>\n\n\n\n<ol class=\"wp-block-list\"
