    50 Performance of Exterior Beam-Column Joints under Seismic Type Loading 1. Design of Exterior Joint The joint shear strength and strong-column weak-beam condition for the earthquake ground motion in the X- and Y-directions were checked as per the draft revision of IS (BIS, ) and were found to be satisfactory. (a) (b). If a building's foundation sits on soft or filled-in soil, the whole building may fail in an earthquake regardless of the advanced engineering techniques employed. Assuming, however, that the soil beneath a structure is firm and solid, engineers can greatly improve how the building-foundation system will respond to seismic waves.

    5. WIND LOAD: Wind load acts on all exposed surface structures. The magnitude of the design wind pressure is given in local codes. The wind loads may be neglected in designing the foundation unless caused loads on foundations exceeding one – third of the load due to dead and live loads combined. The International Code Council (ICC) is a non-profit organization dedicated to developing model codes and standards used in the design, build and compliance process. The International Codes (I-Codes) are the widely accepted, comprehensive set of model codes used in the US and abroad to help ensure the engineering of safe, sustainable, affordable and resilient structures.

Example illustrates the analysis and design of deep foundations for a building similar to the one performance. Maintaining a reasonably consistent level of service load-bearing pressures for all of the Chapter 21 provides the minimum requirements for concrete foundations in Seismic Design Categories D, E and F.

In this paper, a review has been done on the seismic performance of pile foundations in liquefiable soil. The paper provides a useful and current overview of this aspect of design of pile. properties, quantifying strain-dependent soil behavior under cyclic loading, and conducting sufficient in-situ and laboratory testing to accurately capture the variability of the subsurface conditions under the mat foundation.

Book Description. Seismic Performance of Soil-Foundation-Structure Systems presents invited papers presented at the international workshop (University of Auckland, New Zealand, November ).

This international workshop brought together outstanding work in earthquake engineering that embraces a holistic consideration of soilfoundation-structure systems. They were submitted under the following topics: LRFD, Foundations in Power/Telecommunication and Seismic Engineering Design, Deep Foundation Design, Construction, Performance and Behavior in Special Soil/Rock Conditions, Design and Construction State-of-the-Art Practices for Deep Foundations and Retaining Structures.

The performance of pile foundations under seismic loading has been researched since the early s, and the results of these researches have formed a considerable level of understanding.

Under seismic excitation, a pile undergoes stresses both as a result of the vibration of the surrounding soil (kinematic interaction) and that of the. Shallow and Deep Foundations • Elastic and Plastic Analysis.

SYNOPSIS Research on soil-pile-structure interaction under dynamic loading over the past 20 years has led to a variety of analysis approaches of varying complexity to address a range of dynamic problems.

Many of these analysis approaches have been adapted for use for the seismic design of pile foundations. 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.

The seismic performance of four pile-supported models is studied for two conditions: (i) transient to full liquefaction condition, i.e.

the phase when excess pore pressure gradually increases. The seismic design of pile foundations is currently performed in a relatively simple, deterministic manner. This report describes the development of a performance-based framework to create seismic designs of pile group foundations that consider all potential levels of loading and their likelihoods of occurrence in a particular area.

The load-displacement response of liquefied soils surrounding deep foundations has been investigated previously by conducting lateral load tests on a full-scale 3 x 3 steel pipe pile group embedded in sands liquefied by controlled blasting. This paper presents a simple procedure to develop stiffness matrix for bridge foundations under seismic loading conditions.

The methodology is based on the results of a pilot program for the Washington State Department of Transportation in which a design manual was developed to assist the bridge engineers for seismic design of bridge foundations for.

The main objectives of this paper are to explore the available helical piles systems as well the performance of the helical pile foundation systems under monotonic and cyclic axial and lateral loads. In addition, to explore the new helical screw pile systems suitable for seismic retrofitting of existing foundations and for new structures.
