AbstractBanyuwangi is an area that belongs to zone 4 (SNI 03-1726-2002) and areas that are prone to earthquakes and are classified as moderate (SNI 03-1726-2012 and 2019). Other than, Banyuwangi also has the longest coastline on the island of Java, so buildings located in coastal areas have different air pressure that can cause very large winds to blow. So that in planning a building not only dead load and live load that needs to be planned but lateral loads also need to be planned. The survey results contained a tourism support building structure and are located very close to the coastal area of the Banyuwangi Dialoog Hotel. So the focus of this research is the construction of the structure. As for what is analyzed is the value of internal forces and deviations to the lateral loads of earthquake SNI 03-1726-2019 and wind loads based on PPIUG 1983 using the help of structural computer applications. The method used in earthquake load analysis is the spectrum response method. The results of the analysis of the value of the maximum force due to earthquake loads and wind loads are most influential on the column elements that cause inter-floor deviation. The deviation value is reviewed in the building service boundary performance, namely in the x and y directions respectively 10.89 mm and 15.75 mm. When viewed from the service threshold value of 87.5 mm, the structure is classified as safe from the influence of the lateral load of the planned earthquake and wind load. So that the building is feasible as a coastal building that is quite safe for commercial buildings and is able to become a tourist destination because it is so close to the sea. Keywords: Coastal, lateral load, drift, tourismAbstrakBanyuwangi merupakan daerah yang termasuk wilayah zona 4 (SNI 03-1726-2002) dan daerah yang rawan terjadi gempa serta tergolong tingkat sedang (SNI 03-1726-2012 dan 2019). Selain itu, Banyuwangi juga memiliki garis pantai terpanjang di pulau Jawa, sehingga bangunan yang terletak di kawasan pesisir memiliki perbedaan tekanan udara yang bisa menyebabkan angin bertiup sangat besar. Sehingga dalam perencanaan suatu bangunan tidak hanya beban mati dan beban hidup saja yang perlu direncanakan melainkan beban lateral juga perlu direncanakan. Hasil survei terdapat struktur gedung penunjang pariwisata dan terletak sangat dekat sekali dengan kawasan pesisir yaitu Hotel Dialoog Banyuwangi. Maka fokus pada penelitian ini yaitu konstruksi pada struktur tersebut. Adapun yang dianalisis adalah nilai gaya dalam dan simpangan terhadap beban lateral gempa SNI 03-1726-2019 dan beban angin berdasarkan PPIUG 1983 dengan menggunakan bantuan aplikasi komputer struktur. Metode yang digunakan dalam analisis beban gempa adalah metode respon spektrum. Hasil analisa nilai gaya dalam maksimum akibat beban gempa dan beban angin yang paling berpengaruh yaitu pada elemen kolom yang mengakibatkan terjadinya simpangan antar lantai. Nilai simpangan tersebut ditinjau pada kinerja batas layan bangunan tersebut yaitu pada arah x dan y masing-masing adalah 10,89 mm dan 15,75 mm. Jika ditinjau dari nilai ambang batas layan yaitu 87,5 mm, maka struktur tersebut tergolong aman dari pengaruh beban lateral gempa rencana dan beban angin. Sehingga bangunan tersebut layak sebagai bangunan pesisir yang cukup aman untuk bangunan komersil serta mampu menjadi destinasi wisata karena letaknya yang sangat dekat dengan laut.  Kata kunci: Pesisir, beban lateral, simpangan, pariwisata

Current approaches to the estimation of wind-induced wind effects on tall buildings are based largely on 1970s and 1980s technology, and were shown to result in some cases in errors of up to 40%. Improvements are needed in: (i) the description of direction-dependent aerodynamics; (ii) the description of the direction-dependent extreme wind climate; (iii) the estimation of inertial wind effects induced by fluctuating aerodynamic forces acting on the entire building envelope; (iv) the estimation of uncertainties inherent in the wind effects; and (v) the use of applied wind forces, calculated inertial forces, and uncertainty estimates, to obtain via influence coefficients accurate and risk-consistent estimates of wind-induced internal forces or demand-to-capacity ratios for any individual structural member. Methods used in current wind engineering practice are especially deficient when the distribution of the wind loads over the building surface and their effects at levels other than the building base are not known, as is the case when measurements are obtained by the High-Frequency Force Balance method, particularly in the presence of aerodynamic interference effects due to neighboring buildings. The paper describes a procedure that makes it possible to estimate wind-induced internal forces and demand-to-capacity ratios in any individual member by: developing aerodynamic and wind climatological data sets, as well as aerodynamic/climatological directional interaction models; significantly improving the quality of the design via rigorous structural engineering methods made possible by modern computational resources; and properly accounting for knowledge uncertainties. The paper covers estimates of wind effects required for allowable stress design, wherein knowledge uncertainties pertaining to the parameters that determine the wind loading are not considered, as well as estimates required for strength design, in which these uncertainties need to be accounted for explicitly.


In this paper bracing, diagrid and outrigger system have been analyzed for comparing the seismic performance of multistorey buildings. Bracing system is a very efficient system which can be used as a lateral load resisting system in concrete and steel buildings, in this system lateral loads are transferred through lateral bracing by undergoing in tension and compression .diagrid is another effective and efficient system that can be used as lateral load resisting system in steel and concrete tall buildings, in this system lateral loads are transferred by inclined members of the building. Another very effective system which commonly used for resisting lateral loads in concrete and steel high rise building is outrigger system, in this system lateral loads will be resisted by outrigger belt truss and core shear wall. Location and number of outrigger and type of bracing is very important which needs to be optimized in this system. In this paper comparison of bracing, diagrid and outrigger system have been studied on a 24 storey by using a standard package of ETABS 2017.

A cyclic loading experiment involving a timber-steel hybrid structure consisting of a steel frame and a novel light timber-steel diaphragm is presented to quantify the flexibility of the diaphragm and its ability to distribute lateral loads in the elastic-plastic phase of the structure. A lateral load-distribution factor was proposed, and its relationship to the ratio of the stiffness of the diaphragm to that of the lateral load-resisting elements was investigated. The diaphragm was classified based on these variables. The results indicated that the failure modes of the structure were associated with the forms of damage experienced by the lateral load-resisting elements, whereas little damage was observed for the diaphragm. The diaphragm exhibited the ability to continuously adjust the distribution of lateral loads to each lateral load-resisting element; accordingly, each lateral load-resisting element had approximately the same shear force, the same lateral stiffness, and the same lateral displacement during the loading process. As the lateral displacement increased, the stiffness ratio and load-distribution factor both gradually increased, and the diaphragm correspondingly changed from semi-rigid to rigid. At times, as the lateral displacement increased, the diaphragm rapidly became rigid, and it was unnecessarily rigid during the initial loading phase when the in-plane stiffness reached a certain threshold.

The present decade, high rise multi-storey buildings are subjected to many external effects such as earthquake, wind loads, tidal loads, etc., in most cases high rise buildings have more vulnerable to earthquake and wind loads. Most of the reinforced concrete multi-storeyed frame buildings were heavily damaged and many of them completely collapsed during due earthquakes. RC frame buildings were severely damaged due to various deficiencies when proper codal provisions are not designed. A study is need to study the behaviour of the RC framed structure under earthquake load to reduce the damage caused by earthquake forces In this investigation a RC framed building of G+20 storeyed is considered in several seismic zones under different soils as per Indian Standard code IS 1893(part1):2016, using STAAD. Pro V8i as software tool. Finally evaluate the ultimate Base shear using Equivalent static method and Response spectrum method addressing under design forces.

The research paper focuses on internal forces determination in the elements of modular buildings under wind load. It provides a methodology for determining dynamic characteristics of a building and for calculating wind loads. This method is based on the following assumptions: coupling of the modules elements is rigid; coupling of block-modules with foundations is hinged-fixed; connection of blocks to each other is hinged in angular points; the floor disk in its plane is not deformed. On the basis of these assumptions the authors derived approximate and refined equations for determining forces in modules elements under static and pulsation components of wind load. The equation of bending moments determination in the pillar bearing cross-section is obtained by approximation of the graph of moments variation, calculated for the spectrum of the ratio of the pillar stiffness and the floor beam in the range from 1/64 to 64. The paper further introduces the calculation results of forces based on the proposed methodology and on the finite element method. The calculations were done while taking different values of wind load and different number of storeys in a building (from 1 to 4 floors). The obtained results are similar, the error does not exceed 5%.
