Introduction: Nanocomposite films have attracted much attention in recent years. Depending on the composition of the film and fabrication method, a large range of applications has been employed for nanocomposite films. Method: In this study, nanocomposite films reinforced with multi-walled carbon nanotubes (MWCNTs) were deposited on the aluminum substrate through hot press processing. A shear lag model and Euler beam theory were employed to evaluate the stress distribution and load carrying capability of the nanocomposite film subjected to tensile load and bending moment. Results: The influence of MWCNT on the Young’s modulus and load carrying capability of the nanocomposite film was investigated through a parametric study. The theoretical predictions were verified by comparison with experimental tests. A close agreement with difference less than 6% was achieved between the theoretical prediction and experimental measurements. Conclusions: The Young’s modulus and load transfer of the nanocomposite film reinforced with MWCNTs increases with the increase of the MWCNT loading. Compared to the neat epoxy film, nanocomposite film with 1 wt % of MWCNT exhibits an increase of 20% in both the Young’s modulus and load carrying capability.

Angles used as web members in trusses are often welded to the chords with unbalanced welds. This is necessary because of space limitations. It is not known what effect such a weld has on the compressive load carrying capacity of an angle. The standards and specification examined allow an unbalanced weld for an angle. The justification for using such a weld is based on research conducted on angles in tension. For these members, it was concluded that an unbalanced weld does not affect the tensile load carrying capacity of the angle. Research results for angles with different weld patterns subjected to compressive loads are not available in the literature. Eighteen tests were conducted on angle compression members with various weld patterns. It was determined that an unbalanced weld is detrimental to the load carrying capacity of an intermediate length angle but is beneficial for a slender angle. Key words: angles, column (structural), compressive resistance, effective length, standards, welds.

Abstract Synthetic fibers like Kevlar and Vectran are used as load carrying members in Electro-mechanical cables for marine applications. These cables have high strength, high modulus and very low water absorption rate which make them suitable materials for marine applications. The flexible electromechanical cables carry tensile load and electrical power along with data signals. Terminations are used to connect these cables to another cable or terminal. An efficient termination will ensure a load carrying capacity that is almost equal to the breaking load of the strength member of the cable. The presence of stress concentrators due to large diametrical difference between termination body and the braided fiber diameter as well as degradation in material properties reduces the strength and results in failure. This study focuses on a chemical potting method of termination, where an epoxy compound is poured into a socket containing the Vectran™ synthetic fibers. The basic design of epoxy based termination, which has a cylindrical outer shell which secures the epoxy-fiber matrix, was selected for this study. The outer shell has two cylindrical inner surfaces of different diameters connected by a tapered region. Material property for static and fatigue loading was evaluated. Finite element analysis was carried out to understand the maximum stress profile developed in the termination and to improve the design. Baseline data on mechanical properties obtained from experiments was used as input in FE analysis. Results of the finite element analysis suggest a reasonable correlation with experiments.

AbstractSeemann Composites Resin Infusion Molding Process (called SCRIMPTM for short) is a resin transfer molding process which is commonly used in the manufacture of yachts. Fiber-Reinforced Plastic (called FRP for short) manufactured by using SCRIMP has higher fiber-volume-content than that manufactured by using Hand Lay-Up Process (called HLUP for short). In general, the tensile strength and fatigue strength are used to compare the tensile properties of SCRIMP-FRP and HLUP-FRP. In this paper, another viewpoint of comparison is used to compare their tensile properties, especially their fatigue tensile properties. Experiments on the fatigue life and damage phenomena in SCRIMP-FRP and HLUP-FRP were performed. Experimental results show that if the same fibers are used in SCRIMP-FRP and HLUPFRP, SCRIMP-FRP will be much thinner than HLUP-FRP and few air bubbles exist inside SCRIMP-FRP. Although SCRIMP-FRP has higher tensile strength than HLU-FRP, the tensile forces they can bear are approached. That means, processes do not affect the tensile load carrying capacities of FRP. However, SCRIMP-FRP exhibits shorter fatigue life than HLUP-FRP. The reason for that is discussed in this paper and qualitative analysis is performed to explain the author's contentions.

This work presents the results of three connection types in double-shear with dowel fasteners, using the simplified equations from the Eurocode 5. All design parameters were established and compared using three different wood strength and density properties, which constitute the members connections. Eighty-one connections were obtained, allowing to conclude about the number of fasteners needed to the applied tensile load. An increase in the number of dowels was obtained with the increased applied tensile load, lower dowel diameter, lower wood density, and lower strength material in all connection types in the study. The design characteristic load-carrying capacity per shear plane and fastener also decrease with the previously considered parameters.

The article presents the pull-out strength tests carried out on M10 expansion anchors in non-cracked and cracked concrete with a crack width cw = 0.30 mm. The breaking loads and the average pull-out strength of anchors in fibre-reinforced concrete substrates were determined. Fibre content ratios of 15, 30 and 50 kg/m3 were used. In addition, two different classes of concrete (C20/25 and C50/60) were tested. The addition of steel fibres caused a decrease in the pull-out strength by 5% for non-cracked concrete of C20/25 class and fibre content up to 30 kg/m3 and a further 7% for the remaining specified dosage. While for concrete of the C50/60 class, it a decrease in the pull-out strength of up to 20% was observed. For cracked concrete class C20/25 with crack initiation cw = 0.30 mm, the reduction was from 9% to 16% in relation to non-cracked concrete and a maximum of 18% for the fibre content of 50 kg/m3. The difference between the tensile load capacity of C50/60 class cracked and non-cracked concrete was lower than 5% and fell within the measurement error.

Cables can be defined as a flexible structure which can only support tensile load and offers no resistance when compressed or bent in a curved shape. They have several applications in engineering structures for supporting and transmitting load form one point to another such as bridges, trolley wheels, supports suspension roofs and main load carrying cables in any structure. Hence it becomes necessary for extensive design and analysis study on cables. Therefore in the present paper work, cable of length 600m is uniformly loaded along the horizontal is been considered for the analysis with the mass of 18kg/m of its length and supports its own weight. The aim of the work is to determines mid length tension, maximum tension and total cable length for h= 10, 20, 30, 40, 50, 60, 70 and 80 meters using MATLAB. The result shows that as h increases, the tension in mid length and maximum tension is decreasing, whereas total length of the cable is found increasing.

Wire ropes or rope strands are one of the most important load carrying components of transportation systems such as bridge, elevator, crane and mine hoisting. Wire ropes must have high tensile strength in order to carry high tensile load. Wire ropes are mainly subjected to axial tensile load in service. This axial tensile load is exerted upon wires of rope or strand. Due to this reason tensile load causes elongation, strain and stress on the center wire (core wire) and outer wires. In this study, theoretical calculations proposed by Feyrer are adopted in order to determine wire loads, stresses, elongations and strains for axially loaded rope strands. An illustrative example is given.
