Liquefaction Assessment

This overview introduces a series of six papers describing the approach taken in a recent dam safety study to evaluate the liquefaction potential and deformation behaviour for the current seismic setting of Duncan Dam. The dam was originally designed and built in the mid-1960s and is an embankment structure founded on a thick sequence of glacial sediments. The papers were initially presented by a team of B.C. Hydro and their consultants at a specialty session held at the 46th Annual Canadian Conference in Saskatoon in September 1993. The papers provide an excellent summary of the current state of practice in evaluating liquefaction and post-liquefaction behaviour. Key words : embankment, liquefaction, seismic, specialty session.

IMPACT OF ADVERTISEMENTS ON THE ARCHITECTURAL IMAGE AND ITS PERCEPTION BY CONSUMERS (BASED ON THE EXAMPLE OF THE KHARKIV METRO STATIONS),

Current State

The paper considers the issues, particularly relevant for the current state of society, regarding the unrestrained distribution of advertising messages in the architectural environment, especially in the underground space of the metro. As a result of this expansion, copyright is violated, the architectural image is distorted, extraneous meanings are introduced, and a “carnival" style is formed that is not typical for engineering infrastructure facilities. The necessity is postulated to involve the community in the process of forming an opinion regarding these phenomena and making certain decisions. A methodology is proposed for assessing the opinions of consumers, in this case, passengers of the Kharkiv Metro. Questions have been developed in order to record and scale respondents' opinions. Key words: architectural environment, outdoor advertising, brand, architectural image, visual perception, metro space.

Liquefaction Assessment

National Disaster Management Agency (BNPB) statistics show that the majority of earthquake affected buildings are residential houses, whereas in practice, soil investigation is rarely conducted for residential houses in Indonesia. This study is preliminary work on the prospective of Swedish Weight Sounding (SWST) for liquefaction assessment for residential houses. Material used is poorly graded sand. The number of half turns from SWST (NSW) per meter for very loose and loose clean fine sand ranges from 4 to 168 (equivalent to SPT 0-30). Liquefaction potential was assessed using an indirect method by converting NSW into equivalent NSPT and direct method. In general, the factor of safety obtained from the direct method is more conservative (thus giving lower liquefaction potential index) than the indirect method. Torque measured for material in this study ranged from 6-54 Nm, equivalent to a specific energy range from 7-70 N/mm2. Liquefaction assessment using SWST data with torque measurement also indicated the soil is liquefiable. SWST also may be able to detect sand ageing. In summary SWS has a good prospect as a highly portable and low cost investigation tool for liquefaction assessment of residential houses in Indonesia.

Role Of Information

This chapter summarizes the current state of practice in the application of information technology (IT) for knowledge exchange amongst key health care stakeholders: healthcare consumers, health service providers, and researchers. The objectives are to review the practices that facilitate collaboration amongst stakeholders, the role of new technologies in facilitating exchange of information amongst key stakeholders, and the role of three key stakeholders as creators, consumers, and/or translators of information. The emphasis is on exploring an increasingly collaborative exchange of knowledge online.

In Situ Methods

This report examines the state-of-the-art of in situ methods of estimating liquefaction potential in sands. In situ methods are especially important since “undisturbed” samples of loose sand for laboratory testing are virtually unobtainable. Various penetration test methods are examined, such as the SPT, DMT, and the CPT and variants. These methods are completely empirical in nature, and have worked well to date. The current state-of-practice is an SPT-based method. Intrusive, seismic-based tests are also examined: the cross-hole, down-hole tests, and down-hole logger. The seismic velocity-based predictors have a stronger physical basis than the penetration test-based estimation methods, but need a larger database. A non-intrusive test, the Spectral Analysis of Surface Waves technique, seems especially suited for examining sites of large areal extent.

Research on vibration of soils and foundations has yielded several fundamental methods for formulation of interaction problems. This paper is intended to survey the development of the current state-of-practice for design and analysis of dynamically loaded foundations. Extensive studies in this field utilize various linear mathematical models for interaction between foundations and different soil media. The effective analytical, numerical and experimental techniques and their methodologies which are well established for treating problems in dynamic soil-foundation interaction are outlined. Described techniques are categorized based upon formulation procedures and their applications. Some areas are indicated where further research is needed.
