Abstract

This work is devoted to studying the issues of vibrations of pile foundations, taking into account soil conditions for various types of fastening of piles to structures and the development of rational methods for choosing the parameters of piles and their number in earthquake-resistant construction. Based on the results of theoretical studies, resonance curves were constructed for three types of fastening of the "structure-group of piles" system. A special technique was proposed, and a series of field tests were carried out to determine the amplitude-frequency characteristics of the system.

Highlights

Structures erected in seismic areas must, on the one hand, meet the requirements of seismic resistance; on the other hand, meet all the requirements for them in non-seismic areas
The main problem is studying the joint work of a building on subsoil foundations during seismic impacts
Based on the results of theoretical studies, resonance curves were constructed for two types of fastening of the "structure-group of piles" system, including the resonance states of the system based on the experiments carried out

Summary

Introduction

Structures erected in seismic areas must, on the one hand, meet the requirements of seismic resistance; on the other hand, meet all the requirements for them in non-seismic areas. To strengthen the soil throughout the entire area of the construction site, soil piles with a diameter of 800 mm were used In this regard, it became necessary, using the experience of the work carried out, to develop a calculation method and propose a method for testing a building and structure on a. The real conditions for embedding the foundation in the ground are difficult for mathematical analysis In this regard, in the formulation of seismic effects, it is necessary to consider the problem of the interaction of the structure with the soil. According to the accepted methodology in Construction Norms and Regulations, to calculate a structure for seismic resistance, he uses dynamic design schemes mainly to determine the periods and forms of natural vibrations. If the main characteristics are quantitatively taken into account correctly enough, the calculation results will correspond to reality with the necessary accuracy
