Comparison of Multiobjective Optimization Methods Applied to Urban Drainage Adaptation Problems
Publisher: American Society of Civil Engineers
Abstract: This article compares three multiobjective evolutionary algorithms (MOEAs) with application to the urban drainage system (UDS) adaptation of a capital city in North China. Particularly, we consider the well-known NSGA-II, ...
Theoretical Analysis and Testing of Steel Frame with Cold-Formed Steel Shear Walls with Steel Sheathing
Publisher: American Society of Civil Engineers
Abstract: A new structural system, called steel frame with cold-formed steel shear infill walls (SFIW), is developed by using cold-formed steel shear walls with steel sheathing plates on both sides as infill walls in steel frame. ...
Rheology and Porosity of Ultralow Density Foamed Cement Pastes Derived from Ordinary Portland Cement and Hydrogen Peroxide
Publisher: ASCE
Abstract: Foamed cement-based materials possess outstanding flame resistance, fire thermal, and sound insulation, but it is difficult to obtain the desired porosity and pore size due to the complicated equilibrium relations between ...
Displacement Estimation of a Skyscraper during Super Typhoon Mangkhut Based on Limited Measurements of Accelerations and Strains
Publisher: ASCE
Abstract: This paper develops a horizontal displacement estimation framework for wind-excited high-rise buildings based on limited measurements of accelerations and strains and applies it to reconstruct the displacement responses ...
In Situ Observation of Microwedge Effect on Liquid Lubrication
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The influence of the minute elastic deformation of tool surface, named the “microwedge,” on the asperity crushing in liquid lubrication is investigated experimentally. The microwedge plays a role ...
Identification of Thermohaline Sheet and Its Spatial Structure in the Canada Basin
Publisher: American Meteorological Society
Abstract: Thirty-four individual thermohaline sheets are identified at depths of 170–400 m in the Canada Basin of the Arctic Ocean by using the hydrographical data measured with the Ice-Tethered Profilers (ITPs) between August 2005 ...
