A Review of Safety Construction of Billboard Around Banjarmasin

Abstract

A safe and standard billboard construction is very important everywhere as well as in and around Banjarmasin. Therefore, the research using cross-sectional descriptive design to analyze the ratio of axial-flexible stress of pillars was conducted. The inclusion criteria for the billboards are billboards with dimension of 4x6 m2, 5x10 m2 and cross-road horizontal billboard or Bando. Meanwhile the exclusion criteria are billboards with dimension of 2x4 m2, 1x1 m2 and non-steel materials billboards. The result shows that billboard construction that is considered safe as well as standard one is billboard with the dimension of 4x6 m2, 10” pillar, 5x5 cm2 angled steel profile; and five pillars Bando with 18” middle pillar, two f 10” side pillars (2.5” truss). Meanwhile billboard construction which is not considered safe are 5x10 m2 billboard, 18” pillar, 2”truss, 5x5 cm2 angled steel profile; and Bando with three 18” pillars, 2” truss. The improvement for 5x10 m2 billboards is by adding 2” diagonal truss, 18” pillar, 2” truss; for three pillars Bando, the improvement is by adding four f 6” pillar, 18” pillar, 2.5” truss.

Safe Construction And Visual Pollution Of Billboards Along Main Street

“…Furthermore, the billboards that are categorized as unsafe can be upgraded to billboards that have a safe structural strength standard through repair by adding four columns to each pillar (a total of 12 pillars), adding 6 "diameter pillars, and 2.5 pipes diagonally around the pillars. for frame reinforcement (Fajar et al, 2015). Visual pollution assessment via the SBE method can be used, although video-assisted evaluation adopted remains dependent on image and light data, equipment, and composition as well as other factors will have different effects on the presentation of image data.…”

“…Safety level evaluation is carried out on structural components, where the calculation of flexible moment and axial force must meet the requirements of SNI 03-1729-2002 paragraph 11.3. through computer software. Determination of structures that are considered unsafe is a structure that has a ratio limit> 1 (Fajar et al, 2015). Underestimating actual wind loads and seismic loads/dynamic response can lead to identified failure modes, namely the sudden mode due to anchor bolt fracture and the gradual mode due to severe local buckling of the steel column.…”

“…When the melting point is reached at the outermost fiber, the nominal moment resistance is equal to M yx melting moment, with the magnitude 𝑀𝑛𝑦 = 𝑀𝑦𝑥 = 𝑆𝑥.𝑓𝑦.  Next stability; must meet the standard plastic moment capacity 𝑀𝑛 = 𝑀𝑝 = 𝑜𝑟 𝑀𝑛 <𝑀𝑝, where the nominal moment strength is obtained, after the block can be calculated in full plastic conditions (Fajar et al, 2015). In this discussion, a case study of the collapse of a billboard due to the super typhoon Mujigae was found in the field monitoring results, then a data collection on the condition of the collapsed billboard was carried out.…”

“…Some things that are considered in the manufacture of billboards are the dimensions of the billboard and the dimensions of the size of the steel frame. Several previous studies have analyzed a billboard dimension measurement criteria that are considered safe according to standard rules, namely it is stated that there are billboard inclusion criteria, billboard exclusion criteria so that the size of the billboards is obtained, the size and frame model and the sizes of the supporting poles (headband pillars) which are ideal according to standards (Fajar et al, 2015). The collapsed phenomenon of billboards in various installation locations in public places made it interesting to conduct an assessment.…”
