Indefinability Of Effective Stress For Unsaturated Soils, Xiong Zhang, Sandra Houston

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

For decades, researchers have searched for an unsaturated soil effective stress that performs analogously to effective stress for saturated soils and provides some simplifications over net stress and suction approaches. A recent debate is whether problems identified with unsaturated soil effective stress can be resolved via elastoplastic analyses. Effective stress equations are reviewed and categorized as being based on volume change, shear strength, yield, or degree of saturation. These equations are evaluated for consistency with saturated soil effective stress expectations using the Barcelona basic model (BBM), simplified into an integrated elastoplastic framework using the modified state surface approach (MSSA).

In Pursuit Of Eye Tracking For Visual Landscape Assessments, David Evans, Brent Chamberlain

Landscape Architecture and Environmental Planning Faculty Publications

Visual quality and impact assessments have historically relied on experts to formally evaluate the visual properties of a landscape. In contrast, environmental psychologists have studied subjective landscape preferences using ratings and surveys. These two approaches represent, respectively, the “objectivist” and “subjectivist” paradigms within visual landscape research. A gap, however, exists between these approaches: actual observation behaviors. In this paper, we argue for the inclusion of eye-tracking research in visual landscape assessments as a critical bridge between objective landscape qualities and subjective visual experiences. We describe the basics of eye-tracking methods and data types to introduce the role of eye movements …

Revisiting Bodies In Interior Design Practice, Paramita Atmodiwirjo, Yandi Andri Yatmo

Interiority

Addressing human bodies is inevitable in interior inquiries and practices. Integrating knowledge about human bodies into design practice can extend beyond the idea of bodies as merely static entities with fixed dimensions. The idea of bodies as the basis for spatial design practice views the human body as a living entity that dwells, occupies, moves, and engages in space. Knowledge about bodies as the basis of practice also needs to view bodies' presence as sociocultural entities. The emergence of the virtual environment provides another context with a shifting materiality of bodies and interior spaces. This issue of Interiority acknowledges the …

Employing Interactive Architecture Techniques In Architectural Design Methodologies To Retrieve Ancient Egyptian Identity, Dina Elwy Aly Hamed Hussein Dr. Lobna Abd-Allah Abd-Elfattah Agha , Dr. Azza Sobhi Ragab Elsakka

Journal of Engineering Research

Architectural projects often rely on modern technologies like smart architecture and environmental treatments, neglecting the principles and philosophy that reflect civilization, ideas, culture, and traditions. This leads to short-lived buildings that depend on these technologies without any purpose of preserving them. Technicians must constantly renew technology to improve production and without benefits, as threats of superior artificial intelligence have been warned, that autonomous machines may perform tasks without programmers understanding how to reach this level. Instead of relying solely on environmental or smart technology, we should make technology serve the design idea rather than relying solely on it. Considering this, …
