dimana sya mencari artikel yg diminati?

 jikalau dulu sya sering ke perpustakaan kampus, membaca beberapa buku dengan judul yg hampir sama maka hanya akan ada beberapa bagian saja perbedaan antar buku tersebut yg lebih spesifik. sebagai contoh buku dgn materi struktur beton bertulang, jarang yg membahas metode desain flat slab, beam column joint, pilecap foundation. sya perlu memasuki ruangan khusus di sudut perpusatkaan kampus sya tersebut untuk mencari artikel yg sedang sya minati untuk cari tahu, jika beruntung sya mendapatkannya namun juga sering tidak ditemukan karena journal tersebut cukup banyak tersusun dalam rak. bisanya yg sya baca2 adalah jurnal paper Structural Engineering dari ASCE.

.



jika tidak ditemukan sya biasanya akan mencari koneksi internet berbayar saat itu di lantai dasar gedung, kala itu yg biasa saya akses adalah EJSE (Electronic Journal of Structural Engineering). terlihat lebih mudah dengan adanya daftar isi dan arahan kepada artikel yg dimaksud, namun masih terbatas sehingga sya masih perlu menggunakan mesin pencari di website lain, ya.. goooogling

.


The Journal EJSE will be indexed and abstracted electronically on a world-wide basis. The journal will be distributed only in electronic form. This means that several million people can have access to each electronically published paper simultaneously and literally real-time. The electronic media and the Internet enables us to publish papers in a very short time to a very wide audience, world-wide. The time spent on printing, shipping, distributing,  etc. can be saved.

.

artikel jurnal sebenarnya berbayar langganan tahunan, sebaiknya untuk yg mengejar profesi tingkatan jabatan akademis mengikutinya agar updates ilmu dan wawasannya. karena sya sifatnya pribadi dan hanya perorangan maka belum menempuh hal tersebut, begitupula dengan penulisan sya pribadi tidak ada arah menulis resmi dan submit ke penerbit. namun lebih suka menulis lewat weblogs secara bebas dan acak, fungsinya lebih cenderung sebagai catatan sendiri saja yg singkat. sya bekerja di swasta dan non-akademis jadi memang tidak ada hubungan dengan jenjang karir akademis beserta akreditasinya. tidak terlalu concern mengenai pengakuan dan indexing :) lagipula google juga sudah auto melakukannya.


perkembangan begitu pesat, saat ini banyak sekali penyedia artikel secara cuma-cuma dari pemilik asli yg dipublikasikan, ada yg sifatnya draft atau scan author copies. namun ada juga penyedia journal terbaru updates yg juga disediakan cuma-cuma menggunakan prinsip lisensi opendocument creative common. hal tersebut ada karena dukungan finansial dari tiap-tiap institusi kampus dari penulisnya.


berikut daftar link dari website penyedia artikel jurnal tersebut,

dari dulu sya biasanya menggunakan costum commands pada search engine Google, misal berikut adalah mencari file artikel, report, atau lain-lain dalam format PDF pada website AISC dengan tujuan spesifik pada directory Continuing Education



saat ini index Google pada website tersebut menunjukkan hasil sekitar 30 halaman,

besarnya radius tekukan penampang RHS

pada tabel profil baja untuk penampang pesegi berlubang (Rectangular Hollow Sections) atau Hollow Square Sections biasanya tidak ditampilkan nilai besaran dimensi radius tekukan sudutnya. hal ini dikarenakan perbedaan pada alat fabrikasi tiap produsen untuk membentuk tekukan tersebut pada proses dingin, tergantung dari ketebalan dan mutu pelat baja. merujuk pustakan dari Steel Tube Institute, nilai radius tekukan tersebut biasanya berikisar dua kali ketebalan pelat untuk mutu baja A500 (fy=42ksi s/d 46ksi atau ~290MPa s/d 320MPa).

sedangkan merujuk pada Australian Steel Institute (gambar diatas) besarnya 2 s/d 2.5 kali tebal pelat. sedangkan merujuk peraturan EuroCode besarnya nilai radius dalam tekukan bervariasi 1 s/d 5 kali tebal pelat, semakin tebal maka nilai radius tekaukan juga akan semakin membesar.
