Load Initials Settlement For Free

The purpose of such tests is to verify that the load capacity in the constructed pile is greater than the nominal resistance (Compression, Tension, Lateral, etc.) used in the design. The best results occur when pile load tests are performed in conjunction with Pile Dynamic Analysis (PDA).

Initial Load Tests on Piles This test is performed to confirm the design load calculations and to provide guidelines for setting up the limits of acceptance for routine tests. It also gives an idea of the suitability of the piling system.

Initial test is carried out on test piles estimate the allowable load and also to predict the settlement at working loads. Routine test is carried out on working piles to check on working piles and to assess the displacement corresponding to working load.

The load-settlement curve is drawn which is a logarithmic graph where the load applied is plotted on X-axis and settlement on Y-axis. From the graph, the ultimate load for the plate is obtained which is the corresponding load for settlement of one-fifth of the plate width.

For insensitive buildings, the maximum settlement permitted at the head of an individual pile during load testing at DVL should be 10mm plus the calculated elastic shortening of the pile shaft, for piles less than 1000mm diameter. For test piles greater than 1000mm diameter a value in excess of 10mm may be appropriate.

Initial test is carried out on test piles estimate the allowable load and also to predict the settlement at working loads. Routine test is carried out on working piles to check on working piles and to assess the displacement corresponding to working load.

Routine Load Tests on Piles The test load applied is 1½ times the safe carrying capacity of the pile. The Maintained load method as described in Clause 6.2 of IS-2911 (Part IV) ? 1985 shall be followed for loading for the Routine Tests.
