Experimental Evaluation of Dynamic Stiffness of Footings

萨拉热窝大学土木工程学院的Branislav Verbic和莱斯大学的Anestis Veletsos在地震工程和减少灾害方面进行了为期三年的美国-南斯拉夫合作研究项目，其主要目标是评估在沙土和粘土中支撑的建筑地基在地震运动下的反应。研究人员将测试目前的理论解决方案，以确定模拟地震条件下的基础刚度和刚度；并将他们的数据与过去的测试进行比较。如果发现重大分歧，将提出新的改进的理论解决方案。这项提议结合了美国和南斯拉夫科学家的理论和实验专长。在地震胁迫下进行的土壤/结构相互作用研究对美国和南斯拉夫地震敏感地区的建筑和场地建设具有重要意义。该项目得到了美国-南斯拉夫科学技术合作联合委员会的批准，并通过美国和南斯拉夫政府的联合基金提供相应的资助。美国的捐款每年由国务院提供。没有涉及NSF基金。向南斯拉夫主要机构提供赠款。美元资金包括美国科学家前往南斯拉夫的旅费和南斯拉夫科学家在美国的生活费

The principal objective of this three-year U.S.-Yugoslav cooperative research project in earthquake engineering and hazards reduction between Branislav Verbic, Faculty of Civil Engineering at the University of Sarajevo, and Anestis Veletsos, Rice University, is to evaluate the response of building foundations supported in sandy soil and on clays when subjected to seismic motion. The investigators will test current theoretical solutions to determine foundation stiffness and rigidity under simulated seismic conditions; and compare their data with past tests. If significant disagreement is found, new improved theoretical solutions will be proposed. This proposal combines the theoretical and experimental expertise of the U.S. and Yugoslav scientists. Soil/structure interaction studies performed under seismic duress have significant implications for building and site construction in earthquake sensitive areas in the U.S. and Yugoslavia. This project was approved by the U.S.-Yugoslav Joint Board on Cooperation in Science and Technology and is funded through a joint fund of matching contributions from the U.S. and Yugoslav governments. The U.S. contribution is provided annually by the Department of State. No NSF funds are involved. Grants are made to the principal Yugoslav institution. Dollar funds are included for U.S. scientist travel to Yugoslavia and for Yugoslav scientists' living expenses in the U.S.
