The aim of this thesis is to provide a tool for contractors to select optimal equipment for projects, which will increase cost efficiency and reduce environmental impacts. The target geographic area for this research is the state of California, and th . . .

This study focuses on the analysis of rainwater runoff from an extensive green roof system. Over time, space that was formally available for rainwater to properly infiltrate to the ground is being taken up by impervious built surfaces. Green roof tech . . .

Performance Based Design (PBD) using nonlinear analysis techniques is a well– established method to evaluate the seismic performance of RC coupled wall structural systems and their associated components like coupling beams. In principle, it is crucial . . .

Lightweight concrete has been used in construction because of its properties, such as thermal, and fire resistances although it is more expensive and less available than normal weight concrete. One way to save time, cost, and to provide an alternative . . .

Improving the engineering properties of soil through soil modification has been implemented in practice for a number of years. However, construction over soft soil sites has remained a major challenge for projects all over the world because the ground . . .

Reinforced concrete (RC) walls are the most commonly used structural elements in buildings for resisting lateral forces induced by earthquakes. Therefore, reliable and robust analytical models that can predict their behavior under earthquake actions a . . .

Reinforced concrete (RC) structural walls are the most commonly used structural elements in buildings to resist earthquake loading. Concrete crushing in wall boundaries followed by buckling of longitudinal reinforcement is one of the most common failu . . .

According to a research conducted by Durham University, UK, landslides kill approximately ten times more people around the world than was formerly believed. Landslides are recurrently perceived in coastal areas where the water has high salinity. It is . . .

Liquefaction and cyclic mobility are two major modes of ground failure that occur due to earthquake loads. Cyclic mobility is initiated due to a reduction in shear strength of the soil. to evaluate the likelihood of occurrence of such failures, it is . . .

One of the many problems that engineers face is protecting structures from the disastrous effects of earthquakes, especially at soft soil sites. Soft soils are known to amplify the shaking during an earthquake resulting in higher accelerations at the . . .
