Nowadays, modern structures are becoming slender, irregular shaped and long spanned which are susceptible to floor vibration phenomena. The purpose of this study is to determine the minimum slab thickness of a RCC slab to prevent undesirable vibration that will not cause discomfort to occupants and compare the obtained result with (Rakib, 2013) who investigated on this previously. Though American Concrete Institute (ACI) provided code for minimum slab thickness requirement from static deflection criteria, it might not be sufficient for dynamic serviceability like vibration. An investigation based on 3D finite element modeling of a reinforced RCC floor subjected to gravity load including partition wall load is carried out to study the natural floor vibration. The ANSYS model verification is done and is validated by ETABS modeling. The variation of the floor vibration is studied for several parameters such as different slab thickness, span length and floor panel aspect ratio.

Evaluation and approximation of timber connecti...

Aiming a comprehensive analysis of laterally loaded cross laminated timber (CLT) wall systems, the present thesis discusses two core topics. Initially, the evaluation and approximation of timber connection properties are spotted. In particular, basing on an extensive discussion of already available methods, alternatives for determining the initial stiffness and ductility of timber joints are proposed. Furthermore, a capable displacement-based approach, able to approximate the entire course of even complex load-displacement relationships, is developed.Subsequently, the focus is set on CLT wall systems. Besides a summary of currently applied calculation models, a new displacement-based method for predicting the load-displacement behaviour of wall diaphragms is proposed. In order to consider the nonlinear behaviour of connections, the afore-developed continuous function is used. The quality of the suggested wall model is verified by experimental results gathered from full scale wall tests, conducted at three independent research facilities. Within the last part of the thesis it is examined how several factors as, e.g., the wall length, vertical joints, used connections or the vertical load may affect the behaviour of CLT wall systems. Moreover, different approaches for determining the lateral load distribution on CLT wall diaphragms within one floor are discussed.

Quantitative Geology of Late Jurassic Epicontin...
74,89 € *
ggf. zzgl. Versand

The book summarizes about 40 years of the author's research on sedimentary geology in an epicontinental (shelf) sea during the Late Jurassic in northern Switzerland. It presents a synopsis of the interplay of varying paleoclimate, of sea level variations, of varying water depth, of sea floor topography, of vertical and lateral facies changes, of processes of sedimentation like aggradation and progradation, of compaction, of the great regional differences in rates of sedimentation and in isostatic equilibration of the lithosphere under load, and of concomitant synsedimentary tectonics. Regional variation in isostatic adjustment of the lithosphere to the increasing load of sediments is analyzed by means of time correlations based on a detailed biochronology of ammonites in combination with mineral stratigraphy using the comparatively stable clay mineral kaolinite, and with sequence stratigraphy.
