Nowadays, there is a lack of adequate code provisions for the seismic performance and risk assessment steel structures to be used within European countries. At same time, in several occasions, existing moment resisting frames (MRFs) have demonstrated very fragile with respect actions due their inadequate ductility capacity. This combination highlights urgent need an update current Eurocode 8 – ...

Oxygen transfer is an important part of wastewater treatment and accounts for as much as 60% of the energy consumption for the activated sludge process. Prior to 1984, no standard method for quantifying oxygen transfer existed, which created problems in the design and warranties for treatment plants. The ASCE Standard for the Measurement of Oxygen Transfer in Clean Water and the ASCE Standard G...

Channel estimation problem is one of the key technical issues for broadband multiple-input–multiple-output (MIMO) signal transmission. To estimate the MIMO channel, a standard least mean square (LMS) algorithm was often applied to adaptive channel estimation because of its low complexity and stability. The sparsity of the broadband MIMO channel can be exploited to further improve the estimation...

A comparative study is presented of the estimated wind load capacities of low-rise steel building frames based on loading patterns ~magnitude and distribution! established from aerodynamic databases on the one hand, and on patterns specified in the ASCE 7 Standard on the other. The estimated capacities are based on the assumption, verified by numerous sets of calculations, and also used in the ...

This paper describes a method to duplicate the structural performance of a graphite-reinforced cementitious composite as the mix proportions and constituents of its cementitious matrix are varied. This is accomplished by placing a test specimen constructed using a modified mixture over a reinforcing scheme identical to that of a control standard and then matching the end deflection of these sam...

This work concerns an assessment of the behavior of infilled frames. The feasibility of possible immediate implementation of some recent developments both in analysis and design of infilled frames for practical design is investigated. It is now widely recognized that masonry infill panels used in reinforced concrete (R/C) frame structures, significantly enhance both the stiffness and the streng...

Modeling parameters (MP) of reinforced concrete columns are a critical component performance-based seismic assessment methodologies because in these approaches damage is estimated based on element deformations calculated using non-linear models. To ensure model fidelity and consistency results, methods ASCE 41, ACI 369.1, 374.3R prescribe modeling calibrated experimental data. This paper introd...

abstract potential evapotranspiration is one of basic parameter in hydrologic cycle that should be estimate in irrigation design and scheduling, watershed hydrology studies. many applications in diverse disciplines require estimates of evapotranspiration (et) at hourly or smaller time steps. the primary objectives of this study were to compare the american society of civil engineers (asce) and ...

Following the formulation of the constitutive model in the preceding Part I in this issue, the present Part II addresses the problems of computational algorithm and convergence of iterations. Typical numerical responses are demonstrated and the parameters of the model are calibrated by test data from the literature.
