Development of a Database for Drilled Shaft Foundation Testing (DSHAFT)
Drilled shafts have been used in the US for more than 100 years in bridges and buildings as a deep foundation alternative. For many of these applications, the drilled shafts were designed using the Continue reading
Shrinkage Cracking in Concrete TiltUp Construction
ABSTRACT
The purpose of this project is to investigate a particular, undesirable cracking pattern in concrete tiltup panels that, until now, did not have a known definite cause. The cause of this cracking pattern is hypothesized to be due to shrinkage Continue reading
Vertical Farming
Vertical farming in urban environments has sprung out of a need to find alternatives to common practice in industrial agriculture. The way in which industrial agriculture is being conducted today has a wide spread negative impact on the Continue reading
Application of Waste Foundry Sand for Evolution of Low-Cost Concrete
Generation of waste foundry sand as by-product of metal casting industries causes environmental problems because of its improper disposal. Thus, its usage in building Continue reading
Containership Load Planning with Crane Operations
Since the start of the containerization revolution in 1950’s, not only the TEU capacity of the vessels has been increasing constantly, but also the number of fully cellular container ships has Continue reading
Analysis and Design of P/C Cylindrical Shells
The purpose of this report is to compare the design of prestressed cylindrical shell without edge beams with that for a prestressed cylindrical shell with Continue reading
Struvite Precipitation and Biological Dissolutions
Struvite is a salt that is formed out of Mg2+,NH4+ and PO43- and it crystallizes in form of MgNH4PO4.6H2O. Struvite’s (magnesium ammonium phosphate or MAP) precipitation has recently been Continue reading
Municipal Organic Waste Composting as Management Option for Urban Agriculture
The ever-increasing population in the metropolis of Accra, Ghana resulting in con-cerns for finding lasting solutions to manage large volumes of waste produced can be tackled through Continue reading
Using GIS-based Multi-Criteria Analysis
Nowadays, GIS techniques have been widely used in every walk of life. Owing to the rapid urban growth, it is of importance to plan and develop the cities in a reasonable and scientific way. As a result, optimum sites of Continue reading
A Study of the Correlation Between Soil-rock Sounding and Column Penetration Test Data
Lime-cement columns have been used in Sweden to improve poor soil conditions since the 1970’s. The method is inexpensive and flexible, but is difficult to test since the columns are Continue reading
