This book describes the factory planning process with its manifold practical characteristics. Previous planning approaches only emanate from the product model. Future plannings need to allow for dissimilarity of an individual factory more strongly, i.e. the factory will feature even more individual characteristics according to its position in the value-added chain. With the methodology presented in the book new factory types can be realized according to the respective requirements. The described methodology has been developed by the authors. Being an extendible concept, it is very useful for the permanent excess planning, rescheduling and replanning of factories.

Built To Resist Earthquakes : The Path To Seismic Design And Construction
info:
This Briefing Paper 1, Building Safety and Earthquakes, consists of four parts describing earthquakes and their effects on buildings. Parts A and B describe the causes of earthquakes and resulting ground motions and explain how earthquake motions create various forces acting on a building. This Part C describes the types of structural systems and lateral-force-resisting elements used in buildings and how they can be used in combinations. Part D discusses the “load path” of earthquake forces within buildings.
A collection of papers presenting the design methodology of structures and relevant codes for earthquake resistance for practicing structural engineers and students.

Distribution of Earthquake Input Energy in Structures
info:
In developing an energy-based design approach and assessing the damage potential of structures, one must know the distribution of earthquake input energy among energy components: kinetic, elastic strain, hysteretic, and damping. This report examines the influences of the ground motion characteristics: intensity, frequency content, and duration of strong motion and the structural properties: ductility, damping, and hysteretic behavior on the distribution of input energy for a one- and a five-story building using 20 accelerograms, ten with short and ten with long duration of strong motion.
Results indicate that for certain damping ratios, ductility has a significant influence on input energy and its distribution among energy components in a structure. For a given ductility ratio, small damping ratio (less than 5%) has a minor effect on input energy, but a major influence on the energy distribution. Damping ratios larger than 5% have a significant influence on the input energy and its distribution. Three energy ratios that relate to hysteretic energy were computed: the maximum ratio of hysteretic to input energy (Eh/Eir)m, the ratio of the maximum hysteretic energy to the maximum input energy Ehm/Eirm, and the equivalent number of yield excursions Neq=Ehm/(Fy.up) where Fy is the yield strength, and up is the plastic deformation. It is found that (Eh/Eir)m generally reflects the energy demand for the largest yield excursion, and Ehm/Eirm and Neq reflect the energy demand for the entire duration of accelerogram. The study shows that (Eh/Eir)m is independent of the duration of strong motion and period of structure; however, Ehm/Eirm is independent of both only for periods less than 1 s. Results indicate that as the duration becomes longer the equivalent number of yield excursions Neq increases indicating more structural damage.
The influence of ground motion characteristics and structural properties on the distribution of energy parameters for a five-story building with fixed-base, base-isolation, supplemental damping, and semi-active control are examined using the 20 accelerograms. The results show that: 1) the distribution of energy through the height of the building is mostly independent of the frequency content and the duration of strong motion, 2) base-isolation, supplemental damping, and semi-active control reduce the damage potential by reducing the input and hysteretic energy demands and have significant influences on the distribution of energy through the height of the building.

B. Szabo: Influence of Shear Connectors on the Elastic Behaviour of Composite Girders
Doctoral dissertation at Helsinki University of Technology
The effect of deformable and rigid connectors and influence of connection parameters on the behaviour of composite girders is examined. Both the elastic and plastic behaviour are discussed, but the former one is the main concern. Deformable connectors cause slip in the joint, which results in redistribution of internal forces and changes in the deformed shape of the beam compared to the connection with rigid connectors.
The aim of this study is to complement the analytical methods and develop numerical models – based on the author's experimental research – capable to provide reliable parametric studies of three-dimensional structural models of composite girders with deformable and rigid connectors.
At first, the partial interaction problem, behaviour of composite girders in the case of various loading types, recent development and real behaviour of connections of composite girders is discussed in the introduction. It is followed by a detailed literature survey serving the purpose of this study. This survey comprises two main parts: analytical and numerical models of composite girders. Among the analytical models, statical and energy methods are considered. The author also developed a new kind of energy method based on variational calculation for determination of shear force distribution of shear connectors of composite girders. The new method is in compliance with the experimental and the latest theoretical investigations. Next, experimental study on steel-concrete and wood-plywood composite girders conducted by the author at the Budapest University of Technology and Economics and Helsinki University of Technology respectively, are presented as well.
Experimental studies are followed by parametric studies based on analytical and finite element analyses in order to examine how changes in the connector stiffness affect the behaviour of composite girders. Based on these parametric studies, new design formulas are developed for design practice. The main results obtained by the author are: development of energy method based on the variation calculation, elaboration of a parametric study for determining the elastic shear force for all cross-sections and spans, use of photoelastic method to verify shear stresses near to the beam end, simulation of temperature effect, and development of a FEM model providing results that show good compliance with experimental results.
Keywords: steel-concrete and wood-concrete composite girders, bridge, shear connection, flexible connectors, finite element method, parametric study
