The load/deflection behavior of pretensioned cable/pulley transmission mechanisms
… transmission mechanism. In this thesis we model load/deflection behavior of one particular transmission option; closed circuit cable/pulley transmissions. Cable drives are well suited to force and position control applications because of their unique combination of zero backlash motion, high …

An investigation into the material behaviour of reinforced concrete beams
… divided into two parts. First, the experimental load-deflection tests on eleven under-reinforced two-span- and four slightly over-reinforced simply-supported beams are presented. The finite element simulation of these beams using the program, NLFRAM is then presented. This is followed by a …

Statnamic Lateral Load Testing and Analysis of a Drilled Shaft in Liquefied Sand
Three progressively larger statnamic lateral load tests were performed on a 2.59 m diameter drilled shaft foundation after the surrounding soil was liquefied using down-hole explosive charges. An attempt to develop p-y curves from strain data along the pile was made. Due to low quality and lack of …

Prediction of deflection of helical anchors under load
… correct calculation of the distribution of load and serviceability requires proper modeling of axial load-deflection characteristics. To keep pace with advances in structural analysis, there is much need for more practical and scientific work on the load-deflection prediction of deep …

Sustainable slow maintained pile load test
Slow maintained load test is widely used by contractors in Malaysia to ensure the driven pile could accommodate the design load of the structure. Slow maintained load test is a test to determine load-settlement curve and pile capacity for a period of time using conventional load test. Conventional …
