RISFormulation of L1 Norm Minimization in Gauss-Markov Models
Publisher: American Society of Civil Engineers
Abstract: norm minimization adjustment is a technique to detect outlier observations in geodetic networks. The usual method for implementation of
Least-Squares Formula for Zero Error (Z0) of Electromagnetic Distance Measuring Instruments
Publisher: American Society of Civil Engineers
Abstract: The zero error of electromagnetic distance measuring instruments is a near-constant systematic error, which has the same effect on the measured distances. This paper presents a least-squares formula for this correction ...
Methods for Selection of Construction Project Manager: Case Study
Publisher: American Society of Civil Engineers
Abstract: The main objective of this paper is to develop a systematic method for identifying the best among the candidates in the process of construction project manager selection by applying two methods. The proposed method combines ...
New Approximation Method for Structural Optimization
Publisher: American Society of Civil Engineers
Abstract: The main difficulty with the use of mathematical programming for structural optimization problems in which the structural form is specific is the formulation of constraints, such as displacement and stress limitations, as ...
Comparison of Rapid Tests for Evaluation of Chloride Resistance of Concretes with Supplementary Cementitious Materials
Publisher: American Society of Civil Engineers
Abstract: In this research, the performance of three rapid methods for evaluation of chloride resistance of concrete, including the rapid chloride penetration test (RCPT), rapid chloride migration test (RCMT), and electrical resistance ...
New Spread Plasticity Model for Reinforced Concrete Structural Elements Accounting for Both Gravity and Lateral Load Effects
Publisher: American Society of Civil Engineers
Abstract: The spread plasticity models that are generally used for nonlinear analysis include the uniform, linear, and, more recently, power spread plasticity models. Because all of these models are formulated from a linear moment ...
Gene-Expression Programming, Evolutionary Polynomial Regression, and Model Tree to Evaluate Local Scour Depth at Culvert Outlets
Publisher: American Society of Civil Engineers
Abstract: Protection of the downstream of culvert outlets against scour process, as a water conveyance structure, is a highly significant issue in design of culverts. Frequent field and experimental investigations were carried out ...

Novel Lower-Bound Solution for Bearing Capacity of Reinforced Concrete Deep Beams
Publisher: ASCE
Abstract: The present study proposes a novel yet straightforward method for calculating the bearing capacity of deep beams using the theory of lower-bound limit analysis. The equations of the proposed method are obtained from the ...
Fuzzy Behavior-Based Online Command Generation for Unmanned Aircraft Guidance in Rough Terrain Environments
Publisher: American Society of Civil Engineers
Abstract: This research is aimed at developing an efficient online path planner for unmanned air vehicle guidance in completely unknown three-dimensional (3D) rough terrain environments. A novel algorithm is proposed that directly ...
