Synopsis:

The course builds on the knowledge acquired by students of the Dynamics of Building Structures course. The student will get acquainted with the determination of the loading of geotechnical structures from natural and technical seismicity, will get an overview of the properties of dynamically loaded soils and rocks, including the procedures for determining these properties. In addition, the student will learn the basic procedures for assessing the effects of technical seismicity and earthquakes on selected geotechnical structures (slab foundations, frame and retaining walls, embankments, slopes, tunnels).

Requirements:

None

Syllabus of lectures:

Systems with one degree of freedom - analytical solutions, equations of motion

Systems with finite number of degrees of freedom, Rayleigh method, damped oscillations

Dynamic properties of soils

Earthquakes, earthquake mechanism, earthquake intensity and earthquake risk

Dynamic effects of machinery on building foundations

Soil liquefaction, evaluation of the possibility of sand liquefaction by in-situ measurements

Dynamic soil improvement

Design of earthquake resistant structures - foundations,

Design of earthquake resistant structures - retaining and frame walls

Syllabus of tutorials:

1. Determination of the seismic wave velocity based on the reraction measurement, evaluation of the cyclic load on the test plate. Determination of dynamic parameters Determination of dynamic loading of geotechnical structures

2. Determination of the possibility of liquefaction of a given sand layer. Co-constructed structures and soils

3. Design of dynamically loaded branched arm structure by Monobe - Okabe and Seed methods

Design of dynamically loaded gravity wall according to Eurocode 1998 and Westergaard

4. Design of foundation for compressor, design of footing by Budhu and Al.Karni method

5. Calculation of dynamically loaded underground structure (tunnel) by free-field method, demonstration of its use in FEA - GEO FEA

6. Demonstration of calculation of seismically loaded structure using FEA -PLAXIS Questions, summary,

Study Objective:

The aim of the study is to obtain a methodological basis for the application of fundamental procedures in the assessment of common geotechnical structures for seismic effects.
