- Abstract
In recent years, both the height and weight of buildings have increased. This trend is especially noticeable in the central urban areas of Japan. Both tensile and compressive forces occur in foundations such as these piles because of the overturning moment from earthquake and wind loads. To address these situations, new types of foundations need to be developed for high-rise superstructures. One approach is the nodular cast-in-place concrete pile, which has a nodular part at the mid-section of the pile. In situ full-scale load tests were carried out to estimate the bearing capacity of the nodular cast-in-place concrete pile. The bearing capacity was also estimated according to the Design Standards for Railway Structures and Commentary. This paper firstly summarizes the in-situ full scale load tests, and then describes the results of standard bearing capacity based on the data from the in situ full-scale load tests, finally mentions the estimation of ground resistance coefficient for nodular cast-in-place concrete piles.
