Design for Serviceability - A probabilistic approach
… performance of structures is defined by serviceability requirements. To estimate the probability of serviceability failure three main design aspects should be considered: (1) the relevant exposures, (2) the structural response and (3) the performance criteria. This thesis presents …

Vibration Serviceability of Long Span Slender Floors
… long slender floors has led to major vibration serviceability issues in building floors under rhythmic loading. This happens as a result of reduced natural frequencies and damping ratios due to reduced structural rigidity (Devin et al, 2015). Even though these vibrations do not lead to …

On-orbit serviceability of space system architectures
On-orbit servicing is the process of improving a space-based capability through a combination of in-orbit activities which may include inspection; rendezvous and docking; and value-added modifications to a satellite's position, orientation, and operational status. As a means to extend the useful …

Some aspects of vibration serviceability in wood floor systems
Two related areas of research are presented in this thesis. In one area, 106 in-situ wood floor systems were subjectively rated and tested to determine fundamental frequency values. This database of wood floor systems was used to provide further validation of a recently proposed design criterion …

Vibration Serviceability Assessment of a Steel Modular Floor System
A new modular steel floor system, named FastFloor, is proposed for commercial buildings. The system is conceptualized to be prefabricated at the shop and ready to be installed on a previously erected skeleton frame structure consisting of girders and columns or connected to core shear walls. The …

Concrete microstructure homogenization technique with application to model concrete serviceability
… and then applied in the study of concrete serviceability. The concrete homogenization model includes RVE in two scale levels: cement paste RVE in microscale and concrete RVE in mesoscale. Cement paste RVE is composed by microstructural phases (water, unhydrated cement, calcium hydroxide, …

Serviceability-based design of tall buildings subjected to vortex shedding
… Although there are multiple factors that govern serviceability in tall buildings, it has been deduced from the literature, that acceleration is a very important factor, and that as the level of acceleration increases, people become more uncomfortable. Moreover, across wind response caused mainly …

Using STPA and CAST to design for serviceability and diagnostics
… as a key contributor to machine unavailability. Serviceability and diagnostics are an important control to minimize customer losses when problems do occur. Methods are needed that identify serviceability needs early in the product development process while managing product complexity. STAMP …

The effects of partitions on the vibration serviceability of concrete floors
… to vibration problems. As a result, vibration serviceability has become the governing design criterion for many of these new civil engineering structures. It is known that long span, slender floors possess lower natural frequencies and reduced damping leading to vibration serviceability …

Assessment of Analytical Procedures for Designing Metal Buildings for Wind Drift Serviceability
While designing metal buildings for wind drift, for simplicity of analysis and design, connection at base of column is considered as pinned which provides no rotational restraint. The actual behavior of the connection however, is partially rigid, that provides some rotational stiffness even in case …

Serviceability Design of Long-Span Timber Beams Considering Semi-Rigid Beam-Column Connections
… and control of mid-span deflections at the serviceability limit state (SLS). Conventional timber design practice typically assumes idealised pinned supports in deflection calculations, neglecting the partial rotational restraint provided by real beam-column connections. This simplification …

Dynamic response of highway bridges under a moving truck and development of a rational serviceability requirement
Through the development and usage of high-strength materials, the design of more flexible bridges is unavoidable. It is assumed that limiting a bridge static deflection would control the excessive vibration caused by more flexible design. However, results of prior studies indicate that deflection …

Dynamic Testing of In-Situ Composite Floors and Evaluation of Vibration Serviceability Using the Finite Element Method
… floors for the purpose of evaluating vibration serviceability. The measurement, analysis, and computation of a floor's accelerance frequency response function (FRF) is the core premise linking all areas of the presented research. The burst chirp signal using an electrodynamic shaker is …
