RISPSO–BPNN Fusion Algorithm for Tunnel Fire Ceiling Temperature Prediction under Longitudinal Ventilation
Publisher: American Society of Civil Engineers
Abstract: The ceiling temperature in tunnel fires is crucial to determining safety parameters for both occupants and structures. Numerous studies have neglected the effect of longitudinal ventilation velocity in tunnels. This study ...
Using Bargaining Game Theory for Risk Allocation of Public-Private Partnership Projects: Insights from Different Alternating Offer Sequences of Participants
Publisher: American Society of Civil Engineers
Resilience-Based Retrofitting of Adjacent Reinforced Concrete Frame–Shear Wall Buildings Integrated into a Common Isolation System
Publisher: ASCE
Abstract: Adjacent buildings of three to five stories with small spaces between them are widely used as offices, schools, and hospital wards. The seismic resilience of such buildings is critical, and retrofitting adjacent buildings ...
Failure Characteristics and Failure Process Investigation of Fine-Grained Sandstone under Impact Load by Ultrahigh Speed DIC and SEM Techniques
Publisher: ASCE
Abstract: The dynamic failure characteristics and fracture process of brittle materials such as rock involves a complex crack propagation process, the underlying mechanics of which is not yet fully understood. At present, the ...
Principle and Implementation of Incorporating Nanomaterials to Develop Ultrahigh-Performance Concrete with Low Content of Steel Fibers
Publisher: American Society of Civil Engineers
Abstract: The effect of nanomaterials on the microstructure of ultrahigh-performance concrete (UHPC) has been intensively studied, but the relationships between the macroscopic flexural failure process and microstructures of ...
Electromagnetic Wave-Absorbing Property and Mechanism of Cementitious Composites with Different Types of Nano Titanium Dioxide
Publisher: ASCE
Abstract: Ten types of nano TiO2 (NT) were used to endow cementitious composites with the electromagnetic absorbing property. The influences caused by sample thickness, the size, and surface treatment of NT on the electromagnetic ...
Product Compositions from Sequential Biomass Pyrolysis and Gasification of Its Char Residue
Publisher: ASCE
Abstract: Sequential pyrolysis of biomass and gasification of the resultant char generate syngas. The Aspen Plus software was used to simulate a two-stage high-temperature cyclone pyrolysis and gasification of corn straw and rice ...
