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 Performance of RC Structures by Different Modeling Approaches
Ashwini L K, M Keshava Murthy and Ravikumar C M

In elastic method of analysis, loaded structural elements do not reach up to collapse stage and the failure pattern cannot be traced out. Effect of the lateral forces, i.e., wind force and seismic force, makes the structure collapse and structural elements reach beyond the yield point. So, during seismic loads, structural elements show inelastic behavior. For inelastic behavior, suitable stress-strain curves have to be derived and analysis has to be performed. An attempt has been made in this paper to evaluate the behavior of the five-storey RC frame structure using SAP2000 by adopting the nonlinear static analysis and considering different modeling approaches. Mander's and Kent and Park's modeling approaches have been adopted for the performance of nonlinear static analysis and results are tabulated.

Chloride Permeability and Strength Properties of Concrete Using Alccofine: An Experimental Investigation
K Thangapandi and R Anuradha

The paper examines the porousness qualities of solid samples utilizing 'alccofine' and M20 grade cement concrete. The variety was concentrated on the samples exposed to solidification supplanted by different rates of alccofine (0, 10, 12, 14 and 16 rates respectively). Casted samples are relieved in climatic temperature and solidified properties of cement are done at 7 and 28 days, and Rapid Chloride Permeability Test (RCPT) was done at 28 and 35 days. The results showed that the specimen permits 2000 to 4000 Coulombs giving medium rating according to ASTM 1202 (ASTM C1202, 2010). The RCPT showed improved opposition for chloride penetrability and low pace of consumption chance level.

An Experimental Study on Flexural Ductility of High Strength Concrete Beams
Anusuya Senthilkumar, P N Raghunath and K Suguna

The paper makes an attempt to highlight the benefits accrued through confining concrete internally and externally with the use of cellular stirrups and epoxy-bonded Glass Fiber Reinforced Polymer (GFRP) wraps. Full-scale beams of cross-section 150 ` 250 and 3,000 mm in length were used as test specimens. The target parameters included loads and deflections at significant loading stages. The study variables comprised spacing of stirrups and the stiffness of GFRP wraps. All the beams were tested for failure under the action of two-point loading system. The deflections and cracking were observed throughout the loading spectrum. The results showed that the ductility performance improved appreciably with the inclusion of cellular stirrups and epoxy-bonded GFRP wraps.

An Experimental Study on the Strength Properties of Standard Concrete by Partial Replacement of Cement with Calcium Bentonite and Alccofine
M Vijaya Sekhar Reddy and P Divakar

Large amount of carbon dioxide is released in the environment during cement production, resulting in global warming. There is a need to alter the cement by some natural resources having pozzolonic properties. Calcium bentonite powder is a naturally available material having pozzolonic properties able to replace cement partially. The contribution of mineral admixture alccofine to concrete reduces thermal, shrinkage cracks and increases strength as compared to conventional concrete. Alccofine boosts the compressive strength of concrete. The paper proposes that cement be replaced with calcium bentonite (5%, 7.5%, 10% and 12.5%) and alccofine (5%, 7.5%, 10% and 12.5%), respectively. Varaplast SP-123 (superplasticizer) is used for good workability with the concrete, and it is taken by the weight of cementitious material. Cubes and cylinders were cast in accordance with M30 design mix, and compressive strength and split tensile strength were evaluated for 7 days and 28 days curing period; workability tests (slump cone) were conducted and compared with conventional concrete, and based on the test results, various strengths were identified.

A Critical Review of Various Factors Influencing the Mechanical Properties of Fly Ash-Based Geopolymer Concrete
Ramya Madhuri B and Srinivasa Rao K

Although vast research has been carried out on geopolymer concrete, still there is no well-established methodology for selecting the parameters such as molarity of NaOH solution, Na2SiO3 to NaOH ratio, alkali to binder ratio and curing methods. The paper aims at providing a basic idea of the effect of these parameters on the performance of geopolymer concrete.
