In order to meet the high requirements of marine environmental protection and Eurocodes, based on the actual construction conditions of deep water on site in Croatia, the extra-long steel pile foundation was adopted to Pelješac Bridge. At the meantime the corresponding extra-large scale pile driving barge had to be used to carried out during the construction. The pile bearing capacity was analyzed and checked by the actual measured PDA (Pile Driving Analyzer) data. The test results showed that the toe bearing capacity of driven piles had linear relationship with blow counts, and the penetration (displacement/blow) before the stoppage was inversely proportional to toe bearing capacity. In addition, the traditional empirical formula of long-term pile bearing capacity of driven piles was only suitable for the piles, which were shorter than 100m. The stoppage criteria of extra-long pile should concentrate on penetration firstly, while the pile design elevation was subsidiary factor. Therefore, the analysis of pile driving procedure and results could be considered as significant actual engineering reference for the coming works.

Soil investigation has an important role before building a building. The carrying capacity of the soil obtained from the results of soil investigations is very influential on the shape and dimensions of the foundation itself. In the PT.Asahi Forge Indonesia Project, the SPT test data is out of sync with the actual piling results related to embedded pile penetration. The design plan for piles with a length of 7 m based on the N-SPT test turned out that in the field, the piles achieved a bearing capacity at a depth of 9 meters. The final project aims to analyze and compare the carrying capacity of a single pile based on static methods and N-SPT test on the Pile Driving Analyzer. The method used in this research is the study method of laboratory test results and N-SPT. Work steps include; preparation, literature study, data collection, carrying capacity analysis, and comparison of analysis results. The results of the analysis of the carrying capacity of the piles based on the static method by the  (Vijayvergiya & Focht, 1974)  method  amounted to 549,201 kN; The (McClelland, 1974) Method  of 426,292 kN; The U.S Army Corps Method is 459,545 kN and the Tomlinson (1977)  Method is 474,191 kN. While the results of N-SPT were bearing piles bearing capacity with the Mayerhof (1956) method of 738,645 kN and the Schmertmann (1967) Method of 451,327 kN.  Based on these results, the N-SPT test based on the Mayerhof  (1956) Method of 738,645 kN was the closest to the PDA test results of 755,116 kN. The comparison of the results of the analysis between the static test, N-SPT and PDA test is 19: 24: 30. This means that the carrying capacity of the static pile and PDA test has a difference of 37% while between the N-SPT and PDA test has a difference of 20%.

The purpose of this research is to know the ratio of bearing pile capacity with some static and dynamic calculation method to Pile Driving Analyze (PDA) dynamic test result. The analysis uses static calculations using several methods namely, Meyerhoff, Vesic, α Thomlinson, and α Terzaghi, Peck and Mesri methods.Consultant calculation using Reese & Wright method. Dynamic bearing capacity uses jacking pile record  from Hydrolic System Pile Driving (HSPD)  and Pile Driving Analyze test results. The results showed that Reese & Wright method with SPT is the most closely approximated PDA test result with percentage 74,72%; 76.79% and 82.83% for number of pile 310, 368 and 763. While the result of comparison of jacking pile record that most approached PDA is on pile number 638 with a percentage of 82.83%. The largest settlement results are at pile number 310 and 763 with a decrease of 26.3 mm and 25.9 mm with α Vesic+Terzaghi, Peck and Mesri method

The experimental investigation on the effects of granular fill and geogrid reinforced granular fill on the behaviour of the static liquefaction potential of the subsoil is reported in this study. A series of plate load test were carried out with different thickness of the granular fill, number of geogrid layers, and size/dimension of the footing. The test results were presented in terms of bearing capacity and subgrade modulus for the settlement ofδ10,δ15, andδ20. The experimental results revealed that the introduction of granular fill significantly increases the bearing capacity and effectively control the settlement behaviour of the footing. The introduction of geogrid in granular fill enhanced the Percentage of Control in Settlement and Bearing Capacity Ratio by a maximum of 328.54% and 203.41%, respectively. The introduction of geogrid in granular fill interrupts the failure zone of the granular fill and enhances the subgrade modulus of the footing by a maximum of 255.55%; in addition subgrade modulus of the footing was increased with an increase in the number of geogrid layers. Based on the test results it is suggested that the footing with large size has beneficial improvement on the reinforced granular fill.

Deem test results from the low reversed cyclic loading quasi-static test with 2 RC columns as the basic information of secant stiffness damage of the reference column and take use of the TMS instrument in the test to artificially make the damage percentage of secant stiffness of the RC column as 33%, 50% and 66%, 6 damaged columns in total; reinforce the 6 damaged columns and 2 undamaged ones under the same conditions with AFL, through quasi-static contrast test. Test results show that it is able to effectively boost horizontal ultimate bearing capacity and ductility deformability of the RC columns with AFL for reinforcement; besides, there is a linear function relationship between horizontal ultimate bearing capacity, target ductility factor, and damage percentage of secant stiffness.

An experimental program of laboratory bearing tests was performed to characterize the bearing capacity of foundation on unsaturated granular soils. All tests were performed by pushing a circular rod on the surface of compacted sand specimens with different values of matric suction until failure. The test results show an increase in ultimate bearing capacity with increasing matric suction at low suction value but a decrease in that at high level of suction. The comparisons between the test results and simulations using the expressions proposed in this paper are presented and discussed. Good agreements are achieved for all testing values of suction.

The authors present an experimental and analytical study of slotted-in connections for joining walls in the Masonite flexible building (MFB) system. These connections are used for splicing wall elements and for tying down uplifting forces and resisting horizontal shear forces in stabilizing walls. The connection plates are inserted in a perimeter slot in the PlyBoard™ panel (a composite laminated wood panel) and fixed mechanically with screw fasteners. The load-bearing capacity of the slotted-in connection is determined experimentally and derived analytically for different failure modes. The test results show ductile postpeak load-slip characteristics, indicating that a plastic design method can be applied to calculate the horizontal load-bearing capacity of this type of shear walls.

Abstract: 7 square steel tubular columns were tested to discuss the ultimate axial bearing capacity, ductility performance and the steel consumption under stiffened by steel belts and binding bars of different cross-sections. Test results indicate that only by increasing fewer amounts of steel usage, stiffened square CFST columns with binding bars can not only improve the overall effects of restraint and alleviate regional local buckling between the binding bars, but also improve the bearing capacity of concrete filled square steel tubular columns. The utility benefits and the economical benefit is considerable, deserving extensive use.
