Steel Plate Shear Wall (SPSW) is an emerging seismic load-resistant system that, compared to other systems, enjoys the advantages of stable ductile behavior, fewer detailing requirements, rapid constructability, and economy. American seismic provisions decree that a SPSW should be designed as a moment frame with a web infill plate. Specifically, in case of buildings taller than 160 ft, it decre...

Previous studies have underlined the importance of establishing a database high-fidelity benchmark experimental test results under random loading histories such as earthquake excitations for both existing structural systems well newly proposed ones. Such are useful understanding limitations previously developed numerical models, proposing new models more recently systems, better assessing ultra...

This technical note will first review the studies that were done for the Gun Test Facility (GTF) at SSRL, where a photoinjector similar to the one proposed for the LCLS is being tested. In Section 3 the maximum charge out of the gun for a single rf pulse is calculated. In Section 4, PARMELA simulations are used to track the beam from the gun to the end of the photoinjector. Finally in Section 5...

Acase studywas conducted to investigate the seismic behavior of steel plate shear walls having boundary elements designed by two different philosophies. The first design approach does not guarantee that formation of in-span plastic hinges on horizontal boundary elements (HBEs) will be prevented, whereas the second approach guarantees that plastic hinges can only occur at the ends of HBEs. Pusho...

On September 21, 2020, the Pasar Wage Building of Kabupaten Banyumas was hit by a fire causing spalling concrete and thus exposing steel reinforcement. This damage can affect performance safety building. For this reason, an evaluation is needed to determine post-fire structure propose necessary repair retrofitting. Investigation testing in field were carried out study as primary data for seismi...

In this paper, we report a study on performance comparisons of discriminative training methods for phone recognition using the TIMIT database. We propose a new method of phonediscriminating minimum classification error (P-MCE), which performs MCE training at the sub-string or phone level instead of at the traditional string level. Aiming at minimizing the phone recognition error rate, P-MCE nev...

In this paper, we present the Maximum Normalized Likelihood Estimation (MNLE) algorithm and its application for discriminative training of HMMs for continuous speech recognition. The objective of this algorithm is to maximize the normalized frame likelihood of training data. Instead of gradient descent techniques usually applied for objective function optimization in other discriminative algori...

This paper evaluates the application of the Minimum Classification Error (MCE) training to online-handwritten text recognition based on Hidden Markov Models. We describe an allograph-based, character level MCE training aimed at minimizing the character error rate while enabling flexibility in writing style. Experiments on a writer-independent discrete character recognition task covering all alp...

Cylindrical liquid storage tanks are considered as vital structures in industrial complex whose nonlinear dynamic behavior is of crucial importance. Some of these structures around the world have demonstrated poor seismic behavior over the last decades. There are several methods and techniques for rehabilitation and reducing damages in these structures which among them passive control devices, ...
