Ground motions from large-scale blasting operations were used as excitation forces for vibration tests.
A simple pile-supported structure was constructed in an excavated 3 m-deep pit. The test pit was backfilled with % water-saturated clean uniform by: The results of large scale model shell footings were compared with model tests in dimensionless manner.
The improving in the ultimate load capacity of shell footing for both small and large footing was obtained and compared with flat footing. The load ratio for shell footing on reinforced sand were determined at different embedment depth (a/B).Cited by: Individual footings are one of the most simple and common types of foundations.
These are used when the load of the building is carried by columns. Usually, each column will have its own footing. The footing is just a square or rectangular pad of concrete on which the column sits. Cyclic Simple Shear of Large Scale Sand Samples: Effects of Diameter to Height Ratio.

The database consists of 47 load tests on large-scale footings and 50 load tests on small-scale model footings. The large-scale test results are reported by Muhs and Weiss (), Weiss (), Muhs et al.
(), Muhs and Weiss (), and Briaud and Gibbens (). Gandhi () reported the results of the smaller scale model footings. The seismic and deceleration methods are comparatively economical compared with direct load tests on plates or simulated footings.
However, these may be required as controls. Charles employed a simple sand filled waste skip for long term loading which is also comparatively cheap. Laboratory testing was believed to be unrealistic due to disturbance when sampling the chalk.
In situ plate load tests would have been difficult below the water table. The simple and direct approach which was chosen was to load two of the existing pad footings up to the working load of kN (i.e.
tonnes) and measure the settlement. The nominal resistance for large diameter piles is determined from non-destructive testing such as the pile driving analyzer (PDA) or static pile load tests.
Driven piles that are to be load tested need to be driven to the specified tip elevation shown on the plans. The nominal driving resistance will be determined from the pile load test. The second part of the experimental program part consists of tests on large scale reinforced concrete bridge cantilevers without shear reinforcement, with an overall depth of m at the fixed end, a span of m and a length of 10 m.
The cantilevers are tested under different configurations of concentrated loads simulating traffic loads. Throughout the book the emphasis is on practical application, training readers in actual design procedures using the latest codes and standards in use throughout the ts updated design procedures in light of revised codes and standards, covering:American Concrete Institute (ACI) codesEurocode 7Other British Standard-based codes.
Pair of each size and shape of footings was loaded simultaneously. The tests were conducted with center to center spacing between the footing as B, 3B, 5B and 6B for square footing and D, 3D, 5D and 6D for circular footings. Load-settlement observations were made for each test.
Results from test using both square and circular footings are Title: Civil-Environmental engineer l.
