Soil Dynamic

In the present study, response spectra for seismic design in the Bay of Campeche for offshore platforms, using probabilistic models in soil dynamic properties (shear modulus “G”, normalized shear modulus “G/Gmax” and damping ratio “D”), to evaluate their influence in the response of the site of interest, are presented. In this study the probabilistic model of the soil, take into account the uncertainty in soil dynamic properties, due to the fact that the soil dynamic properties play an important role on the interpretation of free-field motion. In this work an explicit form of the seismic wave characteristics were supposed and their likely source-site propagation characteristics were performed with two computer programs. In order to obtain seismic design parameters, three types of seismic event records were associated to the soil properties at the site of interest, taking into account local effect conditions. Geothechnical, seimologycal, tectonical and geological information, similar to the area of interest, were used. The maximum acceleration on the surface, the soil dominant period of vibration, the duration and the frequency content due to a dynamic excitation applied in the rigid base of the soil column were considered. We assumed that each one of the three types of earthquakes are representative of strong motions that might be potentially affecting the Bay of Campeche. In the study thirty-one sampling in several sites located at the Bay of Campeche were used as well as field and laboratory tests. The dynamic properties were determined in each test type by different ranges according to their shearing strain. From these results test, we know the G and D variation law in the range of interest. In the same way, the uncertainty level influence of the soil dynamic properties was modeled with the expected value of the soil dynamic properties. Six different sets including the soil modulus plus/minus a standard deviation, coefficient from the dynamic properties-time variant evaluations, for each one of the shearing strain, which are contained between 10−4 a 10, were considered. Expected site response spectra for different recurrence periods, may be used to complement available information in order to update the present seismic design spectra for offshore facilities located in this area.

The Impact

The publication presents test results and analysis of the impact of military aircraft on an airport pavement made of pre-stressed panels. Three types of aircraft were used in the experiment, i.e. TS 11 ISKRA aircraft, SU 7 BM aircraft and SU-22 M4 aircraft. In the field tests, geophysical methods were used to measure the dynamic properties of the airport pavement structure. Based on the few vibration measurement methods of this type of construction that can be used, the vibration level of the pavement caused by the aircraft operating on that surface was recorded. The tests were carried out for various levels of aircraft thrust, the degree of harmfulness of the impact of generated vibrations on the pavement by sources of excitement, which were the above-mentioned aircraft, was assessed. Due to the fact that the research was one of the first to be carried out in the country, and such research is rare, there are no publications devoted to this issue also in foreign literature. Therefore, there are no reliable and credible criteria for assessing the impact of vibrations on these constructions. In the assessment of dynamic phenomena, by analogy, assessment methods and criteria related to general construction facilities were used. The most frequently used criteria for assessing dynamic interactions are based on the vibration speed criterion. The publication carried out an impact assessment based on the following criteria: vibrator scale, SWD scale and Zeller scale. Keywords: Aircraft; cement concrete Airfield pavement; Frequency
