The high damping force of oil damper vibration control systems in buildings offers relative safety during earthquakes and at a low environmental cost. The oil damper is connected using braces in series and is installed with pins to the building structure, which minimizes the impact on the building structure, and allows installation and removal with ease. This is the first book detailing experimental work and cases of the use of oil dampers in buildings. It shows their effectiveness by detailing the testing and analysis of buildings with them placed at braced positions, exposed to small amplitude vibration, and without them. The only comprehensive presentation of oil damper vibration control Covers analysis and design, with case studies and details of testing and experimental results The book is organized systematically to suit students and junior professionals in structural design as well as more specialist engineers. An additional Python code sample is available online for learning the behaviors of oil dampers (Jupyter Notebook environment required).

Souta and Rikka are officially boyfriend-girlfriend, but they still haven't broken the demon Zepar's curse. Then, one day, Makoto, who had seen Rikka's "grimoire," falls prey to the curse herself. She consults with Souta and they begin to have a side relationship to keep Makoto's symptoms under control. But then Makoto leans into her curse and doesn't even want to be free of it?! When the grimoire's curse catches Makoto in its clutches, Souta, Rikka and Makoto form a love triangle?!

As the curse spreads, Souta, Makoto, and Shino are continuing their twisted relationship when a new student, Koyuki Nonomiya, transfers to their school. She has a contract with the demon Gremory, a friend and rival of Zepar, and wants in on all the fun! Having caught a photo of Souta in the act, Koyuki uses it to blackmail him into further depravity...

After Makoto's confession, Souta is left in a three-way relationship with her and Rikka. But the next to fall victim to Zepar's curse is their homeroom teacher, Tateaki-sensei! Can Souta stand up to the charms of an adult woman!?

An occult tome turns Souta Takatsuki's life upside down when it transforms unrequited love into insatiable passion!

Souta is summoned by Shino for "supplementary lessons" over summer break, and their relationship of domination continues. However, when Makoto discovers their relationship, she starts to seek greater thrills and makes plans for the three to go on a trip...

High intelligence and low wisdom--that's how they roll deep inside the Artificial Evolution Research Center, and no section is deeper than the one in which Asuka's brilliant but flaky mother Kyoko resides. Surely she didn't spend all those years in graduate computer science just to open up a maid cafe? You might think, but remember--she's smarter than you.

After witnessing Souta cheating on her, Rikka is gifted a magic stone by Gremory and begins to dream of doing it with other men. Noticing the change that's come over her, Souta secretly follows Rikka as she accompanies an unfamiliar man into the park at night...
