This work proposes a methodology to optimize a reinforced concrete structure. For this, the Whale Optimization Algorithm (WOA) algorithm was used, an algorithm from the group of metaheuristic algorithms, which presents an easy computational implementation. As a study object, a frame structure adapted from a real reinforced concrete building was used, subjected to the dynamic action of artificially generated synoptic wind. The objective function is to reduce the volume of concrete of the structure. For that, the dimensions of the cross-sections were used as design variables, and the maximum displacement at the top imposed by the ASCE / SEI 7-10 standard as a lateral constraint, as well as the maximum story drift between floors. In addition to this structural optimization, it was also proposed the use and optimization of Tuned Mass Dampers (TMD), in different quantities, positions and parameters, improving the dynamic response of the reinforced concrete building. The results show that for this situation it was possible to reduce the concrete volume of the structure by approximately 24%, respecting the maximum limit of displacement at the top required by the standard.

Rigid Zones

Comparing with reinforced concrete structure, member rigidity of steel structure is less, and displacement of steel structure is larger than that of reinforced concrete structure, so the secondary moment due to axial force has to be considered, i e., the problem of P-Delta effect. For most building structures, especially tall steel buildings, the P-Delta effect of most concern occurs in the columns due to gravity load, including dead and live load. The column axial forces are compressive, making the structure more flexible against lateral loads. If compressive P-forces are present and are large enough, the structure may buckle. Local buckling of individual members or global buckling of the whole structure is possible. This paper presents the method to analysis stability of steel frames with semi-rigid connections and rigid zones by using P-Delta effect.

Reinforced Concrete Structure

Recently, a structure that is generally applied to the construction of multi-storey buildings is reinforced concrete structure. Structural steel is rarely used nowadays, yet in fact, the steel structures are still able to compete with reinforced concrete structures. Therefore, this study aims to determine the exact profile dimensions and the comparison of material prices between steel structures and reinforced concrete structures for columns and beams in redesigning H Building of Dr. Soetomo University, Surabaya. The WF profile steel will be used in this redesigning project. The structure is modeled using AutoCAD, and then imported into SAP2000 software. Modeling structure consists of columns, primary beams and secondary beams. The loads reviewed from the design are dead load, live load, wind load and seismic load. From the results of design review obtained, the overall strength of structure rearrangement is safe and it is obtained the beam profile dimensions of B1 WF 600x200x12x20, B2 WF 400x300x9x14 profile, B3 WF 400x300x9x14 profile, B4 WF 350x200x8x12 profile, and B5 WF 175x125x 5.5x8 profile, K1 WF 400x400x18x28 column profile, and K2 WF 400x400x21x21 column profile. The use of steel structures as a substitute for reinforced concrete structures for columns and beams in the building is a way more expensive with the percentage of steel structure 149.13% more expensive than reinforced concrete structure.

Cendrawasi, Ciputat, Sawah Baru, Tangerangan Selatan, Banten 15413Email : [email protected] of the parameters required in the calculation of seismic base shear on a structure is the fundamental period of the structure. The fundamental period of structure can be obtained through three-dimensional dynamic analysis of the structure. Indonesian Standard Code for Earthquake Resistance Building, SNI 1726-2012, given some empirical equations to calculate the fundamental period ofsome structural system. Some of the given equation can be used for concrete and steel frame structure. However, for the flat plate reinforced concrete structure, sometimes the fundamental period approached as “other structural systems”, which of course can not be shown for accuracy. This study was conducted to obtain an empirical equation that can be used to calculate the fundamental periodof a flat plate structure. The flat plate reinforced concrete structure model being analyzed is vary in total floor number, which varies from 1 to 10 floors, and the width of the building from 20 to 28 meters. From the analysis results obtained relationship between fundamental period, building width and building height in the form Ta = 0,0022(B)’”hn1,15, for the un-cracked section. And Ta = 0,0025(B)’”hn1,28, for the condition of cracked cross-section, with Tn is fundamental period, B is the width of the building plan, and hn is the height of the building.Keywords : Time Period, Flat Plate, Reinforced ConcreteAbstrakSalah satu parameter yang diperlukan dalam perhitungan gaya geser dasar seismik pada suatu struktur adalah besarnya waktu getar alami dari struktur tersebut. Nilai waktu getar alami struktur dapat diperoleh melalui hasil analisis dinamik 3 dimensi dari struktur tersebut. Namun dalam Standar Perencanaan Ketahanan Gempa SNI 1726-2012, juga diberikan beberapa persamaan empiris untuk menghitung waktu getar alami struktur. Beberapa persamaan yang diberikan dapat digunakan untuk sistem struktur rangka beton dan baja. Namun untuk sistem struktur berupa pelat datar (flat plate) beton bertulang, terkadang nilai waktu getarnya didekati sebagai “sistem struktur lainnya”, yang tentu saja tidak dapat ditunjukkan keakuratannya. Penelitian ini dilakukan dengan tujuan untuk mendapatkan persamaan empiris yang dapat digunakan untuk menghitung waktu getar alami suatu struktur pelat datar. Model yang dianalisis berupa struktur pelat datar beton bertulang, dengan jumlah lantai bervariasi dari 1 hingga 10 lantai, serta lebar bangunan dari 20 hingga 28 meter. Dari hasil analisis diperoleh hubungan waktu getar alami dengan lebar bangunan dan tinggi bangunan dalam bentuk Ta = 0,0022(B)’”hn1,15, untuk kondisi penampang utuh. Serta Ta = 0,0025(B)’”hn1,28, untuk kondisi penampang retak, dengan Tn adalah waktu getar alami, B adalah lebar denah bangunan, serta hn adalah tinggi bangunan.Kata kunci : Waktu Getar Alami, Pelat Datar, Beton Bertulang
