Case histories buildings

This is the step by step history of the planning and building of a medium size industrial laboratory. The progress and problems involved in this typical case history will serve to illustrate many of the more general or theoretical examples given in previous chapters. 

The SVE case history discussed is included as a typical situation, similar to many projects encountered in the field that diverge from the ideal case. The site is located adjacent to a vehicle maintenance building in southern California. A 3000-gal and a 5000-gal UST were used to store unleaded gasoline, and a 550-gal UST was used to store petroleum-based paint thinner (Figure 10.15). To add to the situation, different phases of the project were completed by different consultants, and, due to administrative issues, almost 4 years passed between removal of the USTs and completion of the remediation activities.

Our next case history takes what we have learnt about donor-acceptor interactions between arene building blocks in interlocked molecules and exploits that knowledge base in a more conventional intramolecular arena. The self-complexing compound 164+ (Figure 10) incorporates [11] a linear polyether thread intercepted by a DNP ring system, which is co-...

The analysis of case histories (see ref. 16 for examples) can provide some indication of the many interacting factors that determine the rate and severity of resistance build-up. These factors have been discussed by many authors over the years (see for example 17 - 20, and at least fifteen, have been included in a recent scheme prepared by Gisi and Staehle-Cseh (22). 

Slug flow. When partial condensers are located below the reflux drum (Fig. 15.15e), and the velocity in the riser is too slow, vapor and liquid segregate in the riser. A head of liquid builds up and exerts back pressure against the column. Periodically, a slug of liquid breaks through and releases the back pressure. The riser then gradually fills up with liquid, and the cycle repeats itself. This causes fluctuations in column pressure and accumulator level. One troublesome case history of slug flow has been reported (70). 

If one wishes to trace out a complete case history starting with gox influx [Z, = 0 in process (4)], one must solve (22) for with initial condition (0) = atmospheric pressure. Gox influx will never cause a pressure decrease, us pressure will build up to some final pressure p(to) at t = tQ. 

The course has a total amount of 3 ECTS. The instructor s presentations related to the case histories discussed herein take a total of approximately 1,5 contact hours. Students are further requested to work independently on the Yacambii-Quibor case history (see below), to review the paper and to write a short essay with a summary and with their personal opinions and thoughts about it. This is estimated to take, approximately, an additional 4 hours of the student s time. Furthermore, in this course, the case histories discussed herein also serve as an example from which students can build to broaden the scope of discussion. In particular, students are asked to work independently to prepare and deliver a short presentation (of approximately 10-15 minutes) in relation to other geotechnical failure case histories, where the term failure is employed in a broad sense, to indicate cases in which performance was not as expected during design . 

The MDFEA framework and sub-structuring methodology used for the 54-story case study building is shown in Figure 5. Dynamic response history as well as static pushover analyses are conducted using the distributed simulation approach. The characteristics of the model and control DOFs are described in Table 2. 

There are case histories [22, 23] reporting SRB-induced infection of the concrete columns (up to 70% in some areas) of an occupied building. What is thought to be the main mechanism for attacking concrete itself is by the act of SOB bacteria such as Thiobascillus thiooxidans that excrete very low pH acid (H2SO4) which dissolves the concrete [24]. In sewer pipes, SOB can contribute to corrosion rates of up to 1 cm/year [25],...
