Searches for anomalous ionizing particles, strongly interacting massive particles (SIMPs, $\chi$), and magnetic monopoles by the ATLAS and CMS Collaborations with proton-proton collisions recorded at the Large Hadron Collider at a centre-of-mass energy of $\sqrt s$ = 13~TeV are presented. No evidence for such particles has been found, but
lepton-like multi-charged particles with masses between 50 GeV and 980 to 1220~GeV are excluded for electric charge numbers in the range $2 \leq z \leq 7$.
SIMP masses less than 100~GeV are excluded for a scalar mediator with couplings to quarks and SIMPs $g_q = 1$, $g_\chi = -1$.
An improvement by a factor five of the constraints on the direct production of magnetic monopoles with one or two magnetic Dirac charges and stable objects with $20 \leq z \leq 60$ was achieved with respect to a previous analysis, and the charge range has been extended to $60 \leq z \leq 100$.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating
very compact bibliographies which can be beneficial to authors and
readers, and in "proceeding" format
which is more detailed and complete.
