Structural engineering is usually considered as a specialty discipline within civil engineering, but can also be studied in its own right. It is the science and art of designing and making buildings, bridges, frameworks and other similar structures. It has taken a completely different path since the middle of the 20th century. It involves understanding the load-resisting properties of components such as beams, columns, walls, slabs, plates, arches, shells, catenaries, etc., and selecting, proportioning, and connecting different components of a structure to resist the forces and displacements without affecting the safety of the structure. Structural Engineers are responsible for using funds, structural elements and materials creatively and efficiently. In recognition of the growing importance of this branch of engineering, IUP has come up with a quarterly journal, The IUP Journal of Structural Engineering.

Seismic Analysis of Multi-Storey Irregular Building, Including Effect of Shear Wall and Bracing System
Aishwarya Pujari and Tejas D Doshi

In recent years, the application of shear wall system in a Reinforced Concrete (RC) building is widely used to minimize seismic consequence. Furthermore, concentrated steel bracing systems are used in steel structure buildings for the same reasons. Both the systems have a significant impact on the structural performance. Although both systems are used for the same reasons, their effect shows unequal variations and behavior against seismic load. This is the reason that the values of response factors are miscellaneous for varying structural systems. The paper investigates the behavior of RC structures considering the shear wall and steel bracing systems. A comparison is made on asymmetrical plus shape structure, and analysis is done using Response Spectrum Method (RSM) on G+7 RC frame structures. Shear wall and bracings are placed at different locations and frames are modeled using ETABs software. Parameters like base shear, displacement, storey drift, time period and storey acceleration are compared in terms of stiffness and strength.

Kirchhoff-Love Plate Theory: First-Order Analysis, Second-Order Analysis, Plate Buckling Analysis and Vibration Analysis Using the Finite Difference Method
Valentin Fogang

The paper presents an approach to the Kirchhoff-Love Plate Theory (KLPT) using the Finite Difference Method (FDM). The KLPT covers the case of small deflections, and shear deformations are not considered. FDM is an approximate method for solving problems described with differential equations. It does not involve solving differential equations; equations are formulated with values at selected points of the structure. Generally, in the case of KLPT, the finite difference approximations are derived based on the Fourth-Order Polynomial Hypothesis (FOPH) and Second-Order Polynomial Hypothesis (SOPH) for the deflection surface. The FOPH is made for the fourth and third derivative of the deflection surface, while the SOPH is made for its second and first derivative; this leads to a 13-point stencil for the governing equation. In addition, the boundary conditions, and not the governing equations, are applied at the plate edges. In this paper, the FOPH was made for all of the derivatives of the deflection surface; this led to a 25-point stencil for the governing equation. Furthermore, additional nodes were introduced at plate edges and at positions of discontinuity (continuous supports/hinges, incorporated beams, stiffeners, brutal change of stiffness, etc.), with the number of additional nodes corresponding to the number of boundary conditions at the node of interest. The introduction of additional nodes allowed to apply the governing equations at the plate edges and to satisfy the boundary and continuity conditions. First-order analysis, second-order analysis, buckling analysis, and vibration analysis of plates were conducted with this model. Moreover, plates of varying thickness and plates with stiffeners were analyzed. Finally, a Direct Time Integration Method (DTIM) was presented. The FDM-based DTIM enabled the analysis of forced vibration of structures, with damping taken into account. In first-order, second-order, buckling and vibration analyses of rectangular plates, the results obtained were in good agreement with those of well-established methods, and the accuracy was increased through a grid refinement.
