    This paper presents the numerical results of concrete footing-soil foundation seismic interaction mechanism. The concrete footing has been made with two different shapes, but with the equal volume of concrete material. The concrete footing-soil foundation has been analyzed using nonlinear finite elements, with the fixed-base state. The simulated near-fault ground motions have been applied to. Numerical Study to Evaluate Soil Strength due to Seismic Loading V. Yogeshwaran Department of civil engineering, Rathinam Technical Campus, Eachanari, Coimbatore – 21 Abstract— Earthquake is one of the natural disaster which is unpredictable before it occurs. But after and during the earthquake, the damages are very high.

    On the other hand, with the consideration of the interactions between soil and structure under the seismic forces, the problem will be made much more complicated. In the present study, height of the quay walls, soil type, strength and duration of the earthquake on the Bending moment against the wall are considered and pressure distributions. For the development of seismic response analysis method for a whole structural system, however, it is first imperative to clarify the seismic behavior of pile-soil system. In this study, full-scale lateral loading tests were carried out on concrete piles embedded into the ground. The test piles were hollow precast prestressed concrete piles.

Dynamic Behavior of Concrete and Seismic Engineering covers experimental techniques in the study of the dynamic behavior of concrete, examines seismicity and seismic behavior, soil behavior, models of concrete structures subject to seismic activity.

This book is intended to estimate the failure mechanism, hysteresis loops, displacement ductility, deterioration of strength and stiffness and energy dissipation of recycled concrete frames under low-reversed cyclic loading.

A study of the behavior of cemented soils under seismic loading: a six months progress report to United States Geological Survey, Office of Earthquake Studies Author: G Wayne Clough ; Nader Shafii Rad ; Geological Survey (U.S.) ; Stanford University.

This study represents an initial part of a comprehensive investigation of slope behavior in cemented soils, and it is directed toward: (1) documenting of the behavior of natural slopes in weakly cemented soils, (2) defining the engineering response of weakly cemented soils under static and dynamic loading, (3) establishing the stress conditions in steep slopes during static and dynamic loading, Cited by: Behavior of weakly cemented soil slopes under static and seismic loading conditions.

This paper explores the mechanical behavior of a calcareous soil under triaxial loading after treatment with different types of cement, namely Portland cement, gypsum, and calcite. To identify the specific effects of each cement type a.

A Study of the Seismic Behavior Of Geosynthetic Reinforced Walls in Japan The involvement of the author in developing an empirical procedure to estimate displacements under seismic loading is described.

Light-weight facing blocks were found to be effective in reducing displacements in geosynthetic reinforced soil wall structures under. This section summarizes experimental laboratory studies aimed at developing a better understanding of the behavior of architectural glass under seismic loading conditions.

Such studies, in general, characterize the performance of different types of glazing systems during frame racking and describe various failure modes under increasing drifts. in Lebanon under seismic loading. The study was performed using FLAC3D commercial software and the effect of several main parameters has been studied.

These parameters include the soil behavior (elastic versus plastic behavior), soil friction angle, cohesion, earthquake frequency and others. Also, a. No experimental tests or guidelines existed for seismic loading.

The study reported in this paper provides data on the behavior of noncontact lap splices subjected to repeated inelastic tensile. geotechnical designer is also responsible for providing input for evaluation of soil-structure interaction (foundation response to seismic loading), earthquake-induced earth pressures on retaining walls, and an assessment of the impacts of geologic hazards on the structures.

Geotechnical Seismic. To describe the methodology, pile capacities are established, soil springs developed and a combination of pushover, time history, and response spectrum analyses used to describe the expected behavior under anticipated seismic loading. The structure that serves as the basis of this paper is an existing large diameter above grade pipeline.

SOIL RESPONSE CHANGE AND BUILDING FUNDAMENTAL RESONANCES DURING EARTHQUAKE SHAKING Dimitar MIHAYLOV1 and M. Hesham EL NAGGAR2 ABSTRACT The results from the seismic microzonation, including site response and predominant soil resonances, obtained from ambient seismic noise or small earthquakes reflect only the elastic soil behavior.

This paper is concerned with the soil and water behaviour of elevated concrete water tank under seismic load. An artificial seismic excitation has been generated according to Gasparini and. This book sets out to remedy this situation: it begins by presenting the most frequently used experimental techniques in the study of the dynamic behavior of concrete, then continues by examining seismicity and seismic behavior, soil behavior, models of concrete structures subject to seismic activity, seismic calculation methods of structures, and paraseismic cturer: Wiley-ISTE.

Geometric and mechanical characteristics of models. The utilized elevated concrete tank consists of a tank with water capacity of m 3, which is standing on a frame-shaped base with 8 columns with dimensions of × on the seventh floor (with a moment frame system) and height of m above the foundation, to beneath of the is designed and loaded with regard to the ASCE Deep soil mixing to construct stiff columns is one of the methods used today to improve performance of loose ground and remediate liquefaction problems.

This research adopts a numerical approach to study seismic performance of soil-cement columnar reinforcements in loose sandy profiles.

Different constitutive models were investigated in. In the current study, to depict these effects on the seismic response of moment-resisting building frames, a story moment-resisting building frame resting on a shallow foundation was selected in conjunction with three soil types with shear-wave velocities of less than m/s, representing Soil Classes Ce, De, and Ee according to an existing.

The present study highlights the behavior of shallow tunnel in soft soil under seismic conditions by using the finite element (FE) analysis. The developed numerical model is compared with available analytical solutions.
