Abstract text:
This study, presented in two parts, aims to analyse the influence of soil type during earthquake upon piled raft foundations (piles with large diameter - columns) of a high civil building. The analysis is performed on two types of earths indigenous to the area of Iaşi city, Romania. The design takes into consideration a foundation system with friction piles (with lateral friction) placed on a homogeneous soil. The research consists of an infrastructure modelling, highlighting the translation modes and foundation system displacement. The entire structural system is made of reinforced concrete devised at superstructure with frames (columns, beams, plates) and structural walls. The foundation mediums taken into consideration are earths sensitive to moisture and earths with swellings and large contractions. The purpose of this research is to obtain a system that supports loads from the normal service of the building and from seismic forces without any major settlements of any kind. This should be possible by adaptation to the environment of foundation soil and by providing safety against quakes.
Key Words:
