In the future, however, structural design for pile head joints for over-track buildings, which is grouped in buildings such as public facilities, is required to ensure no damage under large earthquakes. The pile constructions of over-track buildings, which often result in largediameter piles, have many restrictions, because they entail constructing cast-in-place concrete piles without footing beams. Then, the pile head joints should also have good workability. In this report, we propose new over-track buildings with the group of small-diameter steel pipe piles with which a largediameter pile is replaced. And we propose how to connect the steel column and the steel pile group with reinforced concrete footing, which is reinforced by U-shape bars around the pile. Cyclic bending shear load tests on the reinforced concrete joints between the steel pipe pile group and the column are conducted to obtain the mechanical properties of the pile head joint with the U-shape bars. Evaluation method of the bending capacity of pile head reinforced concrete joints for over-track buildings with steel pipe pile groups is proposed based on the strength evaluation of the steel square tubular column bases for corner column embedded in concrete footing.
