This study examines how changes in U.S. Federal Reserve monetary policy have affected apartment prices Korea’s Seoul metropolitan area, using monthly time-series data from 2004 to 2024. The federal funds rate, unemployment and inflation were used as independent variables, with price fluctuations the dependent variable. Multiple regression analysis was conducted based on Reserve’s reduction of reserve requirement 0% March 2020. Results show that significantly influenced interest rate...

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...

The paper presents a new beam-column element that combines computational efficiency with accuracy. uses only one monitoring section in each end inelastic zone of the structural member, but accounts for spread deformations under strain hardening response. It is, therefore, variable model benefit integrating moment-curvature response concentrated hinge models beams and columns. is more accurate than current distributed inelasticity simulating monotonic cyclic columns typical curvature...

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...

Abstract Mixed formulations of frame elements offer significant advantages over more traditional displacement formulations, particularly under large cyclic inelastic deformations including the effects shear. This paper complements recent proposal a consistent variational basis for mixed formulation by supplying explicit definition stress field cross‐section. The also addresses numerical stability element state determination algorithm in presence an ill‐conditioned or even singular section...

It has been recognized that urban areas located rather distantly from earthquake sources may, under some special circumstances, be affected by the tremors. A well known example is 1985 Michoacan earthquake, in which a large ( Ms = 8.1) along coast of Mexico caused destruction and loss life City, 350 km away epicenter. Much was due to significant amplification ground motions thick sedimentary deposits down-town area city (Seed et al., 1987). This might peculiar case, but obviously soft-soil...

In next-generation networks, packet classification is important in fulfilling the requirements of multimedia services, including VoIP and VoD. Using pre-defined filters, incoming packets can be categorized that determines to which forwarding class a belongs. Packet essentially problem multidimensional range matching. The tuple space search well-known solution based on multiple hash accesses for various filter length combinations. tuple-based algorithm, rectangle search, highly scalable with...

A nonviscous damping model uses convolution to account for the complete velocity history. The displacement response, and acceleration response of a system with are usually computed by modified direct integration methods. However, existing methods often come strong numerical that reduces accuracy calculated responses. An improved composite method based on Bathe is proposed in this study. In method, using Simpson's rule improve accuracy. combination almost doubles efficiency calculation...

Nonviscous damping is represented by the convolution integral of time history velocity and kernel function. model may correctly represent energy dissipation character linear system for multiple-choice functions. This paper outlines a procedure identifying relaxation parameter ratios cantilever beams with nonviscous in domain. In procedure, approximate value can be identified continuous wavelet transform (CWT) firstly. Then natural frequency tested structure obtained through eigensystem...

The Traffic Speed Deflectometer (TSD) is a mobile vehicle that measures deflection slopes. Deflection slopes have been utilised in previous studies to backcalculate pavement layers' moduli. However, the nonlinear stress-dependency and cross-anisotropy of unbound granular materials fine-grained soils were overlooked those studies. Utilising Finite Element Method (FEM) based on static analysis this study evaluate three-layered flexible system with specific material properties layer thicknesses...

In this paper, we have developed a half-space Peierls—Nabarro (HSPN) model to evaluate dislocation mobility on material surface. The free-surface induced size effect the of an edge in thin films is investigated by using model. thickness layer between and free surface significantly influences dislocation. Peierls stress film may be expressed as function film. A closed-form solution obtained for scaling factor, defined ratio modified conventional one bulk materials, which allows...

This paper proposes a composite frame element for the simulation of inelastic response structural members made up two or more components with different materials, such as reinforced concrete (RC), steel-concrete members, prestressed and fiber-reinforced polymer (FRP) reinforcement. The accounts relative slip at interface between components. Nonlinear geometry effects are accounted through corotational formulation, which permits elements under large displacements. formulation enhances...
