The Geologic Process of The Saka River area: Related to the History Woyla Elevated Ocean in The South Sumatra Island Region, Republic of Indonesia

The lithological and earth structures which compose the geologic process space are terribly fascinating to study. elaborated investigation of pre-tertiary rock subduction at the Woyla web site is rarely carried out. the variability of rocks derived from the Woyla oceanic plate, that folded on the West Sumatra continental plate within the Age of Reptiles era, illustrates the magnitude of the subduction impact mirrored in the structures that are still reflected in the abandoned rocks. The ways want to discover this subduction event are elaborated field observations, skinny section, XRD, and earth science structure measurements, supported by drones and satellite imagery. The lithology of basalt, flint, serpentine, marble, and arenaceous rock is vital to the presence of the Intraoceanic Arch of Woyla within the Saka phase. elaborated structural calculation show that the Saka segment went through several tectonic stages from the Mesozoic to Recent, that is mirrored in the Saka fault and therefore the Penanggungan fault.

Influence of roof slope on timber consumption in plane trusses design

The growing world consumption of wood in civil construction is evident, especially in structural roofing systems. Despite being from a renewable source, its rational and intelligent use is of vital importance in the execution of structural designs. Because it is a system that is recognized worldwide in the design of trussing roof structures, there are several empirical assumptions for structural calculation. To reduce timber consumption, some tile manufacturers suggest a 10% (6°) slope between chords. However, after simulations of 11 slopes with angles from 5° to 15°, the timber consumption was inversely proportional to the slope, reaching a 90% difference between extreme angles. The method used to obtain the results was software designed according to the routines prescribed by the new draft standard of ABNT NBR 7190 (2021). Considering a prefabricated truss with 5 cm thickness sections, the design criterion was that of minimum height, increasing by 0.10 cm until all checks were satisfied. Finally, the minimum angle after which no strengthening is required on the bars was 10°.

Amplification Factor for Wood-Concrete Hybrid Structures Based on Dynamic Numerical Simulation

Extensive concerns on environmental protection have provoked low-carbon buildings to be the mainstream of building construction worldwide, and wooden structures in this sense outperform other structural forms. Wooden-concrete hybrid structures featuring distinct wooden and concrete stories typically exhibit uneven stiffness distribution along the structure height; in particular, abrupt stiffness changes occur at the wood-concrete transition stories. Therefore, structural designing of such hybrid structures must consider a stiffness amplification effect in the static structural calculation as well as complicated procedures in the dynamic analysis. To determine an appropriate amplification factor for design purpose, this study employed a dynamic numerical approach to determine the displacement response of wooden-concrete hybrid buildings and compared the results with the displacement response obtained from static analyses. According to the results, it is found that the appropriate amplification factor should beα= f (x) = 0.47x + 1.00.αcan be valued 1.94 at 2nd floor, 2.41 at 3rd floor and 2.88 at 4th floor. The results may serve as a reference for seismic designing of wooden-concrete hybrid structures.

Flexural capacity and bending stiffness of welded hollow spherical joints with H-beams

Eight specimens were designed, and pure bending tests were completed to study the mechanical properties of welded hollow spherical joints (WHS joints) with an H-beam subjected to pure bending. Parametric analyses of the joints under pure bending were conducted in consideration of the diameter(D) and wall thickness (t) of the welded hollow sphere(WHS), and height (h) and width (b) of the H-beam to validate the numerical model. Calculation methods for the flexural capacity and bending stiffness of the H-beam WHS joints were proposed. Results revealed two failure modes of the joints under pure bending, namely, (1) concave at the connection between the WHS and upper flange and external heave at the connection between the WHS and lower flange and (2) small concave at the connection between the WHS and upper flange and tensile fracture of the welding seam at the connection between the WHS and lower flange. The joints demonstrated good ductility under pure bending. The flexural capacity and bending stiffness of the joints were positively related to the wall thickness of the WHS and to the height and width of H-beam but were negatively correlated with the diameter of the WHS. The errors between proposed formulas and FEA for calculating flexural capacity and bending stiffness are very small, indicating the formulas can be employed in structural calculation instead of FEA.
