Evaluation of the Seismic Response Parameters for Infilled Reinforced Concrete Frame Buildings - 01/0

RC frames with unreinforced masonry infill walls are a common form of construction all around the world. Often, engineers do not consider masonry infill walls in the design process because the final distribution of these elements may be unknown to them, or because masonry walls are regarded as non-structural elements. Separation between masonry walls and frames is often not provided and, as a consequence, walls and frames interact during strong ground motion. This leads to structural response deviating radically from what is expected in the design. The presence of masonry infills can result in higher stiffness and strength and it is cheap and built with low cost labor. Under lateral load, Masonry walls act as diagonal struts subjected to compression, while reinforced concrete confining members (Frames) act in tension and/or compression, depending on the direction of lateral earthquake forces. The main objective of this research is to develop a realistic matrix for the response modification factors for medium-rise skeletal buildings with masonry infills. In this study, the contribution of the masonry infill walls to the lateral behavior of reinforced concrete buildings was investigated. For this purpose, a five, seven and ten stories buildings are modelled as bare and infilled frames. The parameters investigated were infill ratio, panel aspect ratio, unidirectional eccentricity, bidirectional eccentricities. A Parametric study was developed on the behavior of medium rise infilled frame buildings under lateral loads to investigate the effect of these parameters as well as infill properties on this behavior.

This research presents a comprehensive study to perform the seismic analysis of buildings using Direct Displacement Based Method (DDBM), which is a viable and logical alternative to current force-based code approaches. This method is based on a concept of designing structures to achieve a specified performance limit state defined by strain or drift limits. The main objective of the paper is to examine analytically the use of DDBM in seismic design of different types of structural systems (frame, wall, and dual wall-frame buildings) and compare it with the traditional Force Based Design Method (FBDM). Using a developed Excel spread sheets for DDBM procedure, a set of buildings with different heights (2, 4,6,8,10,12,14,16,18, and 20 stories) and different structural systems (frame buildings, wall buildings, and dual wall-frame buildings) are analyzed and the results are compared with those of (Force Based Design Method) FBDM modeled using computer programs SAP and ETABS. This comparison proved that Direct Displacement Based Method is more reliable as it is based on a secant stiffness (rather than initial stiffness) representation of structural response, using a level of damping equivalent to the combined effects of elastic and hysteretic damping. This design method is extremely simple to apply and is very successful in providing dependable and predictable seismic response.

The advances in using composite materials in different structural applications lead to the need of continuous, robust, and structural health monitoring (SHM) systems. One of the most promising techniques for SHM is electromechanical impedance (EMI)technique which depends mainly on the coupling nature of piezoelectric ceramics. Piezoelectric wafer active sensors (PWAS) can be employed as both a well-controlled actuator and sensor at the same time for diagnostic algorithms based on EMI technique. The study presented in this paper interested in EMI technique application to detect damage in composite laminated plates by applying synchronized system of PWAS array operated remotely by exerting harmonic analysis in desired frequency ranges. Frequency ranges are selected upon modal analysis of the healthy tested structure. Harmonic analysis is carried out for different damage scenarios. Extracted electrical charge spectrum data from each PWAS for the previous scenarios can be processed to plot electrical impedance for each case. The modeling process was carried out using a finite element commercial package, ANSYS v.15.0in which multi-physics-based modeling can be used for such structure made of laminated composite material. The extracted resultant spectrum, for healthy structure, is used as a datum in which it is related to its damaged counterparts through damage identification indices such as root mean square deviation (RMSD), and damage detection index (DDI). These indices were used as indicators for the changes in the modal parameters and hence, yielded reasonable results for both damage quantification and localization purposes.

A numerical study for damage of RC columns under demolition blasting has been carried out and the results were compared with available experimental work. Basic considerations for the finite element method of the LS-DYNA Program are introduced. Equations of state models as well as three constitutive material models (the concrete mass, the reinforcing steel, and the high energy explosive material) are described in detail. In the present work, three Finite Element modeling of steel bars as beam, solid elements or by converting reinforcement quantity into concrete solid elements have been examined through comparison with available experimental work. The influence of different parameters on the blasting damage pattern of RC columns has been investigated. These parameters include steel rebar arrangement, explosive factors and the concrete strength of columns. The results have been presented and discussed.

The regular structural integrity monitoring of major engineering structures such as space structures, orbiting spacecrafts, and civil infrastructures have become an urgent necessity to prevent potential catastrophic failures. The evolution of Vibration Based Damage Identification methods (VBDI) introduced an alternative techniques to the conventional methods. These methods relate changes in the vibration signature (natural frequencies and mode shapes) to changes in structural physical parameters (mass and stiffness) and thus is used to identify damage. The present research focus on developing a combined algorithm includes a model-based method (optimal matrix update) and a Non model-based method (frequency response functions difference), to enhance the reliability of the VBDI techniques. The algorithm presented robust sequential scheme of VBDI techniques and has proven a reasonable success when tested through numerical simulation on a large complex space frame. Since, the FEM of the monitored structure considered as a major constitute of the identification procedure, in the present paper, the ability of the proposed combined algorithm to identify damage in plate-like structure is investigated. A numerical simulation is carried out by introducing several damage scenarios to steel plate and predictions were compared to the known damage. Regardless the assumptions made in the FEM and the introduced simulated random errors introduced at different steps in the algorithm procedures, the algorithm is found to be reliable in identifying damage in plate-like structures.

Structural Health Monitoring Using Two Stage Algorithm Combines Non Model-Based and Model-Based Techniques - 01/0

The aging of civil infrastructure and aerospace structures has led to an increased need to monitor the overall structural health. If growing damage not identified on time, it may has serious consequences, both safety related and economic. However, the complexity of large structures and the difficulty in accessing them makes the use of commonly existing conventional Non Destructive Evaluation (NDE) methods such as visual inspection and instrumental evaluation methods, impractical. An effective alternative in Structural Health Monitoring (SHM) is the use of methods that depend on Vibration-Based Damage Identification (VBDI) techniques. These methods use limited instrumentation to detect the changes in the measured modal characteristics of the structure, that is, its frequencies and mode shapes. These characteristics change with the physical properties of the structure (stiffness, mass and damping matrices) and can be used to help find the location and extent of damage. Optimal matrix update method is one of the VBDI algorithms that depends on finite element modelling (FEM) of the structure and is therefore referred to as model-based damage identification algorithm. The FRF differences method is also one of the VBDI techniques that depends on the directly measured frequency response functions data and is therefore referred to as non model-based or modal- based damage identification algorithm. However, VBDI algorithms still faces a number of challenges that have not been fully resolved. Some of these challenges are highlighted through modal tests designed to provide estimates of damage in a 3D eight-bay free-free frame. Details of tests on a healthy structure as well as on a structure in which predetermined damage has been introduced are presented. A proposed algorithm combining the aforementioned model-based and non-model based methods is introduced to improve the reliability of damage detection. The algorithm is first tested through numerical simulation to predicting damage on the basis of modal test data and the predictions are compared with the known damage.
