physical decline and the necessity of redevelopment are never-ending challenges for built communities. neighborhoods undergo cycles of birth, growth, stabilization, decline and rejuvenation. redevelopment is a mechanism that can reduce the time an area is in decline and spur the process of revitalization. furthermore, redevelopment can provide incentives for a developer to build in a community ...

Like blighted urban areas, indigenous nations in the U.S. often have abandoned underutilized commercial or industrial properties with potential environmental contamination within the confines of their reservations. Like urban brownfields, often contamination problems are discovered long after the responsible parties have disappeared. Financial incentives, tools, and risk-management techniques h...

Sustainable urban form has been recognized as one of the major concerns of the planning practice. Current land use pattern trends with low-density, single-use, and leapfroging urban growth on city outskirts call for more efficient land use development strategies balancing economy, environmental protection, and social equity. In this paper, we present a new multiobjective spatial optimization mo...

an experimental study is conducted on three ½ scales, single-story, single-bay, frame specimens. the first specimen was a reinforced concrete frame with solid-brick infill. the second specimen was a reinforced concrete frame with hollow clay perforated-brick infill. the last specimen was a reinforced concrete frame without any infill. these three specimens were tested by pseudostatic method. di...

Stormwater quality in three urban watersheds Denver that have been undergoing rapid infill redevelopment for about a decade was evaluated. Sampling conducted over 18 months, considering 15 storms. Results: (1) The first-flush effect observed nutrients and total suspended solids (TSS) but not dissolved (TDS), conductivity, pH, fecal indicator bacteria; (2) though no significant differences on ev...

Abstract: This paper introduces a new numerical method for the analysis of infilled steel frames with hollow clay blocks. This approach is based on the brittle cracking model of ABAQUS. The results of the in-plane calibration analyses obtained with four experimental tests are presented and discussed. The first test was a bare steel frame used as a control specimen. The second was similar to ...

This paper explores the different perspectives on infill development and its role in urban growth. Despite the intense debate about the potential for and effects of infill development, there is very little empirical evidence about whether policies to promote it have been effective, about the amount and type of infill development and its effect on surrounding communities. This paper first review...

Masonry infill has been widely used as building material due to its cost effectiveness and availability.  The failure of these masonry infill walls during the past earthquakes have underscored the importance of ensuring the safety of the infill walls when it is subjected to lateral loads. In-plane and out of plane failures have been observed in many reinforced concrete framed building with maso...

The remediation and redevelopment of brownfields are important for achieving sustainable neighborhoods. Voluntary cleanup programs (VCPs) have been established by most states as the principal tool for brownfield redevelopment. Therefore, it is important to understand what site and neighborhood characteristics make it more likely for brownfield property owners to participate. We provide policy-m...
