  AbstractIn this study, a non-linear three-dimensional hydrocode numerical simulation was carried out using AUTODYN-3D, whichis an extensive code dealing with explosion problems. A high explosive material (comp-B) is blasted against several concretewall barriers. The model was first validated using referenced experimental tests and has shown good results. Several numericalmodels were carried out to study the effect of changing the shape of wall barrier from flat to convex curve and concavecurve, and also investigated the effect of changing the angle of curvature. The results showed that changing the shape of awall barrier from flat to convex curve has the best performance in mitigating the effect of blast waves. It is also concludedthat convex walls with 60° angle of curvature have the best performance compared to other barrier walls. Manuscript profile

  AbstractIn this paper, a new triangular membrane finite element with in-plane drilling rotation has been developed using the strainbasedapproach for static and free vibration analyses. The proposed element, having three degrees of freedom at each of thethree corner nodes, is based on assumed strain functions satisfying both compatibility and equilibrium equations. Numericalinvestigations have been conducted using several tests, including static and free vibration problems, and the obtained resultsare compared with analytical and numerical available solutions. It is found that efficient convergence characteristics andaccurate results can be achieved using the developed element. Manuscript profile

  The aim of the present study is to examine the behaviour of cold-formed steel (CFS) lipped channel built-up I-section withedge and intermediate web stiffeners under bending. Initially, the section dimension of length, width of the flange and depth ofthe sections are optimized numerically and finally, it is validated with the test results. All the select cross-section dimensionshave satisfied the pre-qualified beam dimensions. Numerical analysis is carried out using the software ABAQUS. Totally,four section geometries are tested experimentally. After validation, a total of 75 parametric studies are carried out using theverified finite element model. All the results are compared with the direct strength method specifications for CFS structuresand the suitable design modifications are detailed. Manuscript profile

  Beam–column joints play an important role in providing lateral stiffness and integrity of frames during dynamic loadingsuch as earthquake. In the high humidity areas, during functioning of the building cracks occur, which leads to the corrosionof the reinforcement due to the environmental exposures. Therefore, one of the main failures mechanism of building duringan earthquake is caused by easily yielding of corroded steel reinforcement, which leads to reduce functionality of the framejoints in transferring the loads. This study proposed a new design to reinforce the beam-column joints with embedded carbonfiber-reinforced polymer (CFRP) rods, due to their extremely high strength and stiffness, along with the fact that they willnot rust or corrode and very light weight. CFRP rods are used in reinforced concrete (RC) frame and ultra-high-performanceconcrete (UHPC) frame subjected to dynamic load. The prototype of the proposed design is constructed as frame with conventionalconcrete and frame with UHPC material to conduct experiments Test as well as numerical analysis to evaluate theperformance of the proposed joints under dynamic loads. The results showed improvement in the performance of the framesreinforced with embedded CFRP in joints in terms of lateral load resistance capacity, ductility behaviour, overall stiffness,and failure mechanism.
