The selection of material is one of the important aspects used to design a building as it is known that every type of material has a different characteristic. The steel material used as the main component of building structure because of its ductility is more than another material which is the main criterion to design an earthquake resistance building. In this paper, an earthquake steel resistant structure building will be design. This building structure will consist of a five-story office with a regular structure configuration. A special moment frame (SMF) used as the resisting structure system of the earthquake loads as the amount of its load is analyzed using the spectrum response method. The steel material used is type of A36 (fy = 250 MPa; fu = 400 MPa), concrete used f’c = 30 MPa. The design process then produces an earthquake steel resistant structure building, which satisfies the requirement of story drift with a maximum number of story drift occurred in the 2nd story which is 93.5 mm less than allowed story drift that is 95 mm. A structure element dimension used is a beam with a profile of W16x7x40 for every level in the X-axis direction, and the beam with a profile is W14x6.75x38 for every level in Y-axis direction, 12 cm thick plates and column with a profile W14x16x211 is regularly used to every level.

Abstract Some of the largest accelerations and velocities ever recorded at ground-response and structural sites occurred during the Northridge earthquake. These motions are greater than most existing attenuation models would have predicted. Although the motions are large, the correspondence between measured acceleration and damage requires further study, since some sites with high acceleration experienced only moderate damage. Also, some peak vertical accelerations were larger than the horizontal, but in general, they are smaller and fit the pattern observed in previous earthquakes. Strong-motion records processed to date show significant differences in acceleration and velocity waveforms and amplitudes across the San Fernando Valley. Analysis of processed data from several buildings in the San Fernando Valley indicates that short-period buildings such as shear-wall buildings experienced large forces and relatively low inter-story drift during the Northridge earthquake. However, long-period (1 to 5 sec) steel or concrete moment-frame buildings experienced large inter-story drift. For this earthquake, accelerations did not always amplify from base to roof for flexible structures like the moment-frame buildings, but the displacements were always larger at the roof. The drifts at many of the moment-frame buildings were larger than the drift limit for working stress design in the building code. The records from a base-isolated building indicate that high-frequency motion was reduced significantly by the isolators. The isolators deformed about 3.5 cm, which is much less than the design displacement. The records from a parking structure show important features of the seismic response of this class of structure.

Modern architecture design lays more emphasis on the authenticity and regionality of the building.The basic tectonic principles are the real material performance and real construction expression. Architecture artistic is based on the internal expressive force of the structural system. And the logicality of building structure is given the inner beauty of architectural image. Modern timber-structure building is breaking the fetter of formalism in the aspect of structure performance. Its tectonic methods are making the positive exploration in terms of the architectural context inheritance.

Apartments are an option for vertical housing. Currently, with the rapid development of technology, a person will tend to choose housing that can support their mobility. So it is planned that an apartment building structure is planned using a Special Moment Frame System using Performance Based Design referring to SNI 1729: 2015 and SNI 1726: 2019. Planned with columns HC 582x500x50x65 and HC 508x462x75x75 as well as WF beams 400x300x12x22 and WF 400x200x12x22. The results show that the columns and beams are strong but wasteful.

Maximum seismic inelastic drift demand in a steel building with braced frames as primary seismic-force-resisting (SFR) system tends to concentrate in few stories without considering inherent participation of designed gravity-force-resisting (GFR) system in actual structural stiffness and strength. The influence of GFR system on stiffness and strength can be taken into account by considering the composite action in beam-to-column shear connections that exist in modern steel building construction to form actual semi-rigid moment-resisting frames. Therefore, modeling semi-rigid moment frames as an equivalent to the GFR system in braced frame buildings could be utilized as a representative to the strength provided by gravity frames. This paper presents a seismic evaluation of a six-story chevron braced frame, with and without semi-rigid moment frame. Four different cases are investigated under a set of ground motions and results are discussed in terms of story drift distribution along the height. The results pointed out that the current findings lay a foundation to conduct further investigation on the seismic performance of braced frames as designed SFR system together with GFR system.

In terms of the moment frame system of steel structures, early brittle fractures developed in the H-shaped beam-to-column connection during the Northridge and Kobe earthquakes, thereby indicating insufficient seismic performance of these components. In this study, experiments were conducted on two-side shear connections of web and rib plate reinforcements of the flanges on an H-shaped beam-to-column connection. According to the test results, the H-shaped beam-to-column connections with two-side shear connections of beam web and rib plate reinforcements of the flanges were superior to the existing connections in terms of initial stiffness, energy dissipation capacity, and plastic rotational capacity. The test values exceeded 4.2%, 0.027 rad, and 125% in terms of story drift ratio, total plastic rotation capacity, and full plastic moment of the beam, respectively. Accordingly, the proposed H-shaped beam-to-column connection showed better performance than that of the intermediate moment frame regarding seismic design.

Factual Content

In this article, we highlight an underappreciated individual difference: structure building. Structure building is integral to many everyday activities and involves creating coherent mental representations of conversations, texts, pictorial stories, and other events. People vary in this ability in a way not generally captured by other better known concepts and individual difference measures. Individuals with lower structure-building ability consistently perform worse on a range of comprehension and learning measures than do individuals with higher structure-building ability, both in the laboratory and in the classroom. Problems include a range of comprehension processes, including encoding factual content, inhibiting irrelevant information, and constructing a cohesive situation model of a text or conversation. Despite these problems, recent research is encouraging in that techniques to improve the learning outcomes for low-ability structure builders have been identified. We argue that the accumulated research warrants the recognition of structure building as an important individual difference in cognitive functioning and that additional theoretical work is needed to understand the underpinnings of structure-building deficits.

The paper describes the shaking table performance of a half-scale two-story steel moment frame with asymmetric friction connections (AFCs) at the column bases and at the beam ends. The results showed that the beam ends and the base-column joints exhibited bilinear and trilinear response respectively. Residual drifts were less than 0.2% for shake table trials up to 3% peak inter-story drift. Even at a peak inter-story drift of 6.5%, the residual drift response was still only 0.7%.
