Materials science research is becoming increasingly data-driven, which requires more effort to manage, share, and publish data.NOMAD a web-based application that provides data management for materials data.In addition core functions like uploading sharing files, NOMAD allows entering structured using customizable forms providing the software with electronic laboratory notebook (ELN) functionalities.It automatically extracts rich meta-data from supported file formats, normalizes converts...
This paper presents a direct displacement-based design (DDBD) approach for the buckling restrained braces (BRBs) braced glue-laminated timber (glulam) frame (BRBGF) structures. First, critical parameters of DDBD were derived BRBGFs. Then, using experimentally verified numerical models, pushover analyses and nonlinear time-history (NLTHAs) conducted on series one-storey BRBGFs to calibrate stiffness adjustment factor λ BRB-timber connections spectral displacement reduction η. Finally, was as...
In this work, a fast algorithm to evaluate the dynamic response of nonviscously damped systems with arbitrary distributions damping characterised by kernel functions (both number and form) is proposed. The proposed requires mere matrix–vector operations. It can be integrated into existing analysis tools various time integration methods in forms either element-based dashpots or global model. Compared other methods, does not explicitly convolution integral thus require storage whole velocity...
Summary By utilizing a modified Hu‐Washizu principle, new mixed variational framework and corresponding high‐performing four‐node membrane element with drilling degrees of freedom, named as GCMQ element, are proposed. In this work, the generalized conforming concept, which is originally proposed within displacement‐based formulation, extended to formulation. The able handle higher‐order displacement, strain, stress distributions. interpolations complete up second order for strain. enhanced...
This study proposes a new assembly method to address the problems of using conventional direct for assembling elemental damping matrices global matrix. These include challenges in calibrating an ratio desired ratio, significantly low and high ratios associated with lower higher modes, respectively, unintended huge coupling effects between modes. The is based on recently proposed bell-shaped model. It gives consistent used structure. maintains modal orthogonality such that all modes are...
The seismic assessment and retrofit of existing bridges has become important in Taiwan, since the Chi-Chi earthquake 1999. In order to ensure safety traffic network, a project been launched assess re- sistance capacity over 2,200 on Taiwan Roadway System. A detailed evaluation procedure, using modified ATC-40 spectrum method was first applied 140 regular bridges. state-of-the-art nonlinear static anal- ysis (pushover analysis) adopted calculate resistance terms PGA, compare demand according...
A new type of proportional damping models, called bell-shaped model, has recently been proposed. This model not only addressed the spurious forces, but also maintained same order computational efficiency as Rayleigh model. further improved such that, by using tangent stiffness approach, it becomes suitable for structures experiencing softening response with negative stiffness. The allows users to have flexible control modal ratio all interested frequency intervals, including those associated...
This study focuses on the analytical identification and quantification of one type spurious responses in context response history analysis. The is caused by linear interpolation input loads. Through derivations numerical simulations, it shown that identified fully can significantly affect both damping inertial forces. Furthermore, not bounded, thus, resistance-based designs could potentially be non-conservative. findings are applicable to (non-)linear MDOF systems. To address this issue...
This work presents a general finite element formulation based on six--field variational principle that incorporates the consistent couple stress theory. A simple, efficient and local iteration free solving procedure covers both elastic inelastic materials is derived to minimise computation cost. With proper interpolations, membrane elements of various nodes are proposed as examples. The implemented used conduct numerical experiments investigate performance in-plane drilling degrees freedom...
