There exist a wide variety of computational tools for the simulation and design of exits. However, due to the scarcity of behavioral data, these tools rely heavily on the assumptions about human individual and social behaviors. Many of these assumptions have been found inconsistent or incorrect. This paper presents a multi-agent based framework for studying(More)
Many computational tools for the simulation and design of emergency evacuation and egress are now available. However, due to the scarcity of human and social behavioral data, these computational tools rely on assumptions that have been found inconsistent or unrealistic. This paper presents a multi-agent based framework for simulating human and social(More)
Safe egress is one of the key design issues identified by facility planners, manager and inspectors. Computational tools are now available for the simulation and design of emergency evacuation and egress. However, these tools rely heavily on assumptions about individual human and social behaviors, which have been found to be oversimplified, inconsistent and(More)
This paper describes a distributed service architecture that enables the delivery of building design services over the Internet. The architecture of an individual service is three-tiered. The first tier is a common communication protocol interface. The middle tier is the common product model interface. The third tier is the core of the design service. With(More)
This paper outlines an integrated client/server framework for an automated code-checking system. Most previous studies have been focused on the processing of design codes for conformance checking. In this work, we examine additional issues: the criteria of a building model, representation of code provisions, the relevance of the provisions with respect to(More)

Accessibility regulations are federally enacted by the Americans with Disabilities Act (ADA). Design of buildings and facilities must comply with the guidelines developed by the authors of ADA. This paper discusses a hybrid approach using encoding prescriptive-based provisions and supplementing them with performance-based methods to support compliance and(More)
This paper introduces a large-scale engineering systems distributed object framework that serves as the connecting infrastructure between individual engineering tools and analysis components. The framework can incorporate software services as well as hardware solutions. Implemented software services include motion planning simulations and animation(More)
