A field investigation of vertical footing response on sand

the use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach

abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...

Investigation of the management scenarios for the aquifer recovery using mathematical modeling (Case study: Abarkuh aquifer)

Ground waters are considered as substantial water resources in many parts of the world especially in arid and semi-arid area such as Iran. The population growth, the intensive use ofsurface water and groundwater resources has often affected ground water levels. To meeting water management objectives it is essential to have a comprehensive study on the aquifer recharge and ground water withdrawa...

Pumping simulations using 3D analysis on multi-pumping wells

In this research, we chiefly proceed on-site measurement and analysis to examine how the pumping wells influence groundwater properties. The examined region is surrounded by mountains formed by a bowl shaped depression in the Paleozoic strata and granite. The paleozoic strata basin rock is an impermeable bed upon which there is a permeable diluvium and then alluvium. It is estimated a lot of gr...

Seismic Behavior of Prefabricated Column-Footing Connection

Results of an experimental investigation of the seismic performance of prefabricated column-footing connections are presented. Tests were conducted on six 1/4-scale prefabricated column specimens inserted into prefabricated footings in two Groups. Group-1 consisted of four specimens, which were tested under constant axial load and cyclic inelastic lateral displacements. The remaining two specim...
