<p>The corrosion of steel reinforcement is a persistent issue plaguing concrete structures today. The availability of non-corrodible fiber-reinforced polymer (FRP) reinforcement presents an opportunity to mitigate or even eliminate the issue of corrosion, however there is minimal uptake of these bars specifically in seismic applications due to their brittleness. Glass FRP (GFRP) bars, being one of the more common and economical of the FRP products, is being explored at the University of Canterbury for its potential use in earthquake- resistant design. In particular, the cyclic bond of GFRP bars with concrete is being tested using a modified RILEM beam bond test to determine whether they are able to maintain adequate bond with concrete under seismic loading. This paper will discuss the potential use of GFRP bars in seismic applications, drawing form work around the world, and introduce the salient features and behavior of cyclic bonding of GFRP bars as preliminary observations from the bond tests conducted.</p>

Two six-story eccentrically braced dual steel systems (EBDSs) were tested as part of the U.S.-Japan Cooperative Earthquake Research Program. The first, a full-scale structure ( prototype) was pseudo-dynamically tested in the Large Size Structures Laboratory of the Building Research Institute in Tsukuba, Japan. The second, a similitude scaled replica of the first, was tested on the earthquake simulator at the University of California at Berkeley. The prototype was designed for the minimum earthquake forces specified by the 1981 Japanese Aseismic Code and satisfied the current earthquake-resistant design regulations in the U.S.A. (1985 UBC, 1984 ATC 3-06 and 1986 SEAOC). The performance of the EBDS (both prototype and model) was outstanding in terms of its elastic strength and stiffnesses during minor earthquake shaking and its ability to absorb and dissipate energy, without strength and stiffness degradation, during severe earthquake shaking. Substantial overstrengths of both EBDSs with respect to their nominal yielding strengths were observed during severe earthquake shaking. However, the response modification factors currently adopted by the ATC and SEAOC significantly overestimated the experimental values in both instances.

The World

The seismic resistance of prestressed concrete is receiving attention frcm code writers as a result of the research being done on this subject both overseas and in New Zealand. Of particular interest are the activities of the Seismic Commission of the Federation International de Precontrainte (F.I.P.) which reviews information collected from the various parts of the world. The Commission's document "General Principles of Earthquake Resistant Design of Prestressed Concrete Structures” was presented at the Vth Congress of the F.I.P. (Paris, 1966). It is at present being revised for presentation at the VIth F.I.P, Congress, Prague 1970. Drafts of this report are currently being circulated to F.I.P. Seismic Commission members for comment.

Structural Detailing

The development of codes for the earthquake resistant design of concrete structures in New Zealand since the 1931 Hawke's Bay-earthquake is traced. The background to the developments in the design procedures through the years is discussed. Californian seismic design codes, lessons from past earthquakes, and the results of analytical and experimental research work, much of it conducted
in New Zealand, have led to the current philosophy for seismic design in New Zealand as expressed by the 1976 SANZ loadings cods and the SANZ concrete design code about to be published. These codes state requirements for both adequate strength and ductility, and emphasize the importance of structural detailing to achieve satisfactory performance of structures during severe earthquake loading. This New Zealand seismic design philosophy for concrete building and bridge structures is reviewed. A summary of the seismic design provisions of the new SANZ concrete design code (NZS 3101) is given in an Appendix.

This paper reviews the main issues to be addressed in the design of shallow and deep foundations which may be subject to earthquake loading. Information is presented on the soil properties required as well as the various design analysis techniques with a view to assessing the current state-of-the-art and highlighting areas in which further techniques need to be developed. The paper sets out, by way of an overview, a sequence of steps that a designer may follow in developing a foundation system. It is concluded that, at present, the greatest deficiencies lie in the areas of most potential use to designers. A secondary aim of the paper is to enhance communication between geotechnical and structural engineers on aseismic foundation design.
