Abstract:
Often, an apparently compatible relationship between mat and soil deteriorates due to the plague of construction details and the design-construction relationship. This paper reviews subgrade reaction in case studies of four landmark buildings in Houston. Concepts related to mat foundation analysis using the finite element method are discussed to acquaint the practitioner with the related soil-structure interaction concepts. Also included is an examination of structural considerations in connection with mat foundation design.

SP152 Design and Performance of Mat Foundations is the first state-of-the-art review. Within its 267 pages, you will find informative papers dealing with mat foundations and its interaction with the superstructure, design considerations for soil-structure interaction problems, subgrade reaction, subgrade modeling, foundations for tall buildings, mass concrete pour techniques for the mat foundation geotechnical-structural interactions for innovative mat design, and large mat on deep compressible soil. Obtain your copy of SP-152 and see how the science has progressed to the use of present day technological advances. All captured in the 10 technical papers from distinguished international engineers.

In large concrete pours, the heat of hydration, which continues to build for several days, is a major cause of concern for structural engineers. As the surface of concrete cools off, a thermal gradient is formed across the concrete section which can cause the concrete to crack. This paper verifies that by keeping concrete warm and preventing heat from escaping rapidly, the temperature difference within the mass can be minimized, thus reducing the potential for thermal cracking. Use of this technique made possible the largest monolithic mat foundation pour in Hawaii, without construction joints and without artificial cooling of concrete.

The MesseTurm, the tower at the fairground in Frankfurt am Main, Germany, is Europe's tallest high-rise building. It is 256 m (840 ft) tall and rests on a combination mat and bored pile foundation bearing in Frankfurt clay. This paper describes the foundation design and construction. Load and settlement monitoring devices were installed; the measurement results obtained during and after construction are presented. The effect of a post-construction 12-m (40-ft) groundwater lowering on the behavior of the foundations is shown.

Describes three innovative mat foundation designs and the close interaction required between the structural engineer and the geotechnical engineer. The significance of load deformation prediction reliability in the three different soil profiles is illustrated. The cases reviewed include a three-story office building with single basement build on a mat over peat; a 26-story apartment building with basement built on a modified mat in a thin dense sand stratum over soft clay; and a 19-story hotel with two basements built on a mat in a sand layer over medium clay. The mat of the 19-story hotel was supplemented with selective high capacity piles at the column locations designed to ultimate soil capacity at working loads and utilized to reduce both mat settlement and design mat thickness. The instrumentation used to confirm design assumptions in the three cases is briefly described.
